Bank Balnce in trial balance

Hello there Mr.Moffat

So I was doing the section B in Kaplan and there was this list of items in the question that involved me to identify whether the items belonged in the trial balance or not

One of the questions was to identify whether a bank balance of 70(credit) is included in the trial balance

I said no because I thought that if there is a credit in bank balance it should be listed down as an overdraft

If it is a debit only we can state it as a bank balance or else it should be stated as an overdraft clearly if it is credit

My answer was wrong so I suppose it isn’t compulsory to name the bank balance as an overdraft if it is a credit balance and we could also just leave the bank balance like it is as a credit balance

I just wanted you to confirm whether my thought was correct about why my answer was wrong
