How do I clear/delete undeposited funds from the bank deposit?

I have a way to clear the transaction, EileenHess.

You'll want to edit the Deposit to account of the recorded payment. This removes the transaction that shows up in the bank deposit section.

Here's how:

1. On the left panel, click Sales and select Customers.
2. Click the customer's name and look for the payment.
3. In the Receive Payment page, change the account from the Deposit to drop-down list to any bank account.
4. Click Save and close.

When you go back to the Bank Deposit page, you will no longer see the payment. 

To know why some payments go to the Undeposited Funds account, you can check this article: Deposit payments into the Undeposited Funds account in QuickBooks Online.

If you have other questions or concerns, please don't hesitate to ask. Have a great day!
