Let's resolve the bank balance discrepancy, @Hollyg123.

One of your account's users may have created this journal entry. If you don't have this amount from your bank statement, then you can delete it.

Here's how:

1. Open the journal entry that causes the discrepancy.
2. Click the More button.
3. Select Delete and then choose Yes to confirm.

You can refer to this article for more information about reversing a journal entry or deleting it entirely: Reverse or delete a journal entry in QuickBooks Online.
