count++;
towerOfHanoi(x-1,helper, destination, source);

you just need to handle count variable carefully.
look into correct use of count variable.
the correct code is:

import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner cin = new Scanner(System.in);
int n = cin.nextInt();
int x = towerOfHanoi(n,“T1”,“T2”,“T3”);
System.out.println(x);
}
public static int towerOfHanoi(int x , String source, String destination, String helper){
if(x == 1){
System.out.println("Move "+1+"th disc from “+source+” to "+ destination);
return 1;
}

int count = towerOfHanoi(x-1,source, helper, destination);
System.out.println("Move "+x+"th disc from “+source+” to "+ destination);
count += towerOfHanoi(x-1,helper, destination, source);
return count+1;
}
}

Thanks.
