QB is linked to bank account. Customer made only one payment but QB transaction list is showing two payments. How do I delete one payment as it is wrong.

I understand how important it is to correct your books, especially since this has been going on since February. Given that the duplicate is already sitting on your Transaction List, you won't see an option to exclude it right away. Here is how to handle it safely:

1. Find the duplicate payment on your Transaction List.
2. Click Undo under Action column. This kicks it off your list and sends it back to your Bank Transactions (Pending) tab.
3. Go to that Pending tab, tick the box next to it, and click Exclude. This completely removes it without affecting your books.

If QuickBooks warns you that this transaction has already been reconciled, please stop. Altering a reconciled entry will throw off your balances for that month. If that warning appears, I highly recommend consulting an accountant to safely untangle it and keep your books accurate.
