Dice Game: Obtaining the sum of scores

I have been working on a dice game which allows for two players to play.

Here are my game rules:

- Player rolls 5 dice and the values are added to their totalScore;
- Rolling a 1 or 4 will result in those dice being removed and nothing is added to their totalScore.
- Player continues to roll their remaining dice until they have no dice remaining.
- Players turn ends when they have no dice remaining and they receive their totalScore

My question is, how can I obtain a Player's totalScore to output on a label once their turn is completed?

Please note, I have just started to program, so I am very new. I appreciate the feedback.

Here is my code so far,

public partial class Form1 : Form
 {
    Image[] diceImages;
    Label[] labels;
    int[] dice;
    int diceTotal;
    bool rolledOneOrFour;
    Random r;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        diceImages = new Image[]
    {
        Properties.Resources.blank,
        Properties.Resources.one,
        Properties.Resources.two,
        Properties.Resources.three,
        Properties.Resources.four,
        Properties.Resources.five,
        Properties.Resources.six
    };

        dice = new int[5];
        r = new Random();
        diceTotal = 0;

        labels = new Label[]
    {
        lbl_dice1,
        lbl_dice2,
        lbl_dice3,
        lbl_dice4,
        lbl_dice5
    };
    }

    public void btn_roll_Click(object sender, EventArgs e)
    {
        rollDice();
    }

    private void rollDice()
    {
        bool OneOrFourRolled = false;
        int rollTotal = 0;
        int sum = 0;
        int playerScore = 0;


        for (int i = 0; i < dice.Length; i++)
        {
            if (rolledOneOrFour)
            {
                if (dice[i] == 1 || dice[i] == 4)
                {
                    dice[i] = 0;
                }

                if (dice[i] == 0)
                {
                    continue;
                }
            }

            int rollDice = r.Next(1, 7);
            dice[i] = rollDice;
            sum += rollDice;

            if (dice[roll] == 1 || dice[roll] == 4)
            {
                TwoOrFiveRolled = true;
            }
            rollTotal += dice[roll];
        }

        if (!TwoOrFiveRolled)
        {
            diceTotal += rollTotal;

            //listview to show live results
            lb_liveResults.Items.Add("You scored " + sum + " points for this roll");
        }

        penalty = true;

        for (int i = 0; i < labels.Length; i++)
        {
            labels[i].Image = diceImages[dice[i]];
        }
    }
