How do I match receipts if the banks put in my deposit for the wrong amount then withdraws the excess?

Hello there, littlemynxcafe.

You can go back to the receipt and edit the amount that the bank incorrectly deposited.  Then, you can add another line that is a negative amount for the bank withdrawal. This way, the receipt is adjusted and is matched with the bank transactions.

I've attached a screenshot below: 

For reference in matching transactions, please see this article: Add and Match Downloaded Banking Transactions.

You can get back to me if you need more help.
