    printf("Enter input data of size less than 1024 bytes and write end to end the data: ");
    fgets(input,1024,stdin);
    
    /* create buffer and copy */
    InData = (char *)malloc( strlen(input) + 1);

What is the type of InData ?
Assuming it is char *

Your function should be something like (not the best solution but with minimum changes in your code):

#include <string.h>
#include <stdio.h>
#include <stdlib.h>

static char* get_input()
{
   char input[1024];

   /* get string */
   printf("Enter input data of size less than 1024 bytes and write end to end the data: ");
   fgets(input, 1024, stdin);

   /* create buffer and copy */
   char * InData = (char *)malloc(strlen(input) + 1);
   strncpy_s(InData, 1024, input, 1024);
   return InData;
}

I would mimic the C runtime API (i.e. memory handling is caller responsibility):

C

char * get_input(char * buffer, size_t buffer_size)
{
   /* get string */
   printf("Enter input data of size less than %u bytes and write end to end the data: ", buffer_size);
   return fgets(buffer, buffer_size, stdin);
}
