C# one form two tables

Tables are the same. One is current data other is history data.
I am trying not to duplicate the code if possible
Form A:
using SpeadIMLibrary;
using SpeadIMLibrary.DataAccess.Models;
using SpeadIMUI.FormTools;
using SpeadIMUI.Interfaces;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;

namespace SpeadIMUI.Forms
{
public partial class AccessorialsMenuForm : Form
{
// Stores the instance of the parent form (LoginForm)
private Form _parent;

// Stores the userID of the currently loggid in user
private readonly string _userId;

public AccessorialsMenuForm(Form parent, string userId)
{
InitializeComponent();

_parent = parent;
_userId = userId;
}

private void accessorialsMenuGOButton_Click(object sender, EventArgs e)
{
if (createModifyReviewAccessorialsRadioButton.Checked)
{
var mainresult = GlobalConfig.Load_MainTable.GetByLoadNumber(loadSearchBoxValue.Text);

//TODO fix locking form

if (mainresult != null)//load is in load_mail
{
if (createModifyReviewAccessorialsRadioButton.Checked && (!string.IsNullOrWhiteSpace(loadSearchBoxValue.Text)))
{
// Pass LoadNumber to LoadProcessingForm
LoadProcessingForm frm = new LoadProcessingForm(this, _userId, loadSearchBoxValue.Text);
if (frm.IsDisposed == false)
{
frm.Show();
}
loadSearchBoxValue.Text = "";
createModifyReviewAccessorialsRadioButton.Checked = true;
return;
}
}
else //test to see if in history
{
var historyresult = GlobalConfig.History_Load_MainTable.GetByLoadNumber(loadSearchBoxValue.Text);

if (historyresult != null) //load is in history_load_main
{
// Pass LoadNumber to LoadProcessingForm
LoadProcessingForm frm = new LoadProcessingForm(this, _userId, loadSearchBoxValue.Text);
if (frm.IsDisposed == false)
{
frm.Show();
}
loadSearchBoxValue.Text = "";
createModifyReviewAccessorialsRadioButton.Checked = true;
return;
}
}
//TODO: Use textbox to locate load then pass info to form
//LoadFinancialSummaryForm frm = new LoadFinancialSummaryForm(this, _userId, add additional parameters here );
//if (_parent is SpeadIMStartForm mainForm)
//{
// mainForm.openForms.Add(frm);
//}
//frm.Show();
createModifyReviewAccessorialsRadioButton.Checked = false;
return;
}
else if (accessorialsReportsRadioButton.Checked)
{
// TODO: Change ApplyPaymentForm to a reports menu form
//ApplyPaymentForm frm = new ApplyPaymentForm(this, _userId);
//openForms.Add(frm);
//frm.Show();
accessorialsReportsRadioButton.Checked = false;
return;
}
else
{
MessageBox.Show($"A Radio Button must be selected.");
return;
}
}
}
}

Form B: just code to populate form:
public void DisplayRecord(string loadNumber)
{
var loadresult = GlobalConfig.Load_MainTable.GetByLoadNumber(loadNumber);

if (loadresult != null)

Form B:
public void DisplayRecord(string loadNumber)
{
var loadresult = GlobalConfig.Load_MainTable.GetByLoadNumber(loadNumber);

if (loadresult != null)
{
if (loadresult.InUseBy == "0") // Record not in use
{
// Hold the record for current user
GlobalConfig.Load_MainTable.TakeOwnership(loadresult.LoadMainId, UserId);

// Store the LoadMainId of the current record
CurrentRecordId = loadresult.LoadMainId;

// Populate form
_firstPickUpAccountCode = loadresult.FirstPickUpAccountCode;
_lastDeliveryAccountCode = loadresult.LastDeliveryAccountCode;
loadNumberValue.Text = loadresult.LoadNumber;
shipmentNumberValue.Text = loadresult.ShipmentNumber;
loadStatusValue.Text = loadresult.LoadStatus;
shipperAccountCodeValue.Text = loadresult.ShipperAccountCode;

_shipperZipCodeValue = loadresult.ShipperZipCode;
shipperEmailsValue.Text = loadresult.ShipperEmails;
{
if (loadresult.Send214)
send214Checkbox.Checked = true;
}
bCOValue.Text = loadresult.BCO;
// Get lists based on BCO
LoadAssignmentLists();
LoadOtherSRCList();
// Continue populating
billToAccountCodeValue.Text = loadresult.BillToAccountCode;
billtoName1Value.Text = loadresult.BillToName1;
_billToName2Value = loadresult.BillToName2;
_billToPhoneValue = loadresult.BillToPhone;
_billToAddressValue = loadresult.BillToAddress;
_billToCityValue = loadresult.BillToCity;
_billToStateValue = loadresult.BillToState;
_billToZipCodeValue = loadresult.BillToZipCode;
{
if (loadresult.Send210)
_billToSend210 = 1;
}
totalWeightValue.Text = loadresult.TotalWeight;
totalVolumeValue.Text = loadresult.TotalVolume;
totalQuantityValue.Text = loadresult.TotalQuantity;
totalPickUpsValue.Text = loadresult.TotalPickUps;
