What should I do if payments are showing twice in my bank register. One as a deposit and one as a payment. How do I correct?

Welcome to the Community forum, @joe106. I'm here to lend a hand.

In QuickBooks Online (QBO), there are different ways when receiving an invoice payment. These could be one of the following:

• Making a Deposit
• Via Receive Payment feature
• Creating a Sales Receipt

In your case, when you've used the Receive payment feature and deposit the payment to Undeposited Funds. You can create a Deposit in the system so you can match it on the downloaded transaction to resolve the issue. 

For your guidance to prevent duplicate entries in your register, you can check below steps:

1. Create an Invoice or Sales Receipt.
2. Receive the payment and choose Undeposited funds account in the Deposit to drop-down.
3. Make a Bank Deposit for the payment to deposit to the correct bank account.
4. When the bank transaction is available in the For Review tab, match it to the deposit you've created in step 3 by clicking on Find match.
