Greetings, @MonicaG.

You have two options in recording the returned check. Let me provide these to you and help you further.

When the deposit you processed was successful and is on your bank statement, you can void the deposit. Let me show you how:

1. Click on List from the menu bar.
2. Select Chart of Accounts.
3. Look for the account where the deposit is posted.
4. Click on the deposit, then click on Edit from the menu bar.
5. Select Void Deposit.
6. Click on Record.
7. Select Yes on the pop-up.

Secondly, if the deposit hasn't been posted on your bank statement, you can write a check with the same accounts on the deposit.
 
Here's how you can write a check:

1. On the Home Page, click on Write Checks.
2. Select the Bank Account. 
3. Enter all necessary information.
4. Click on Save and Close.

If you have any other questions or concerns, please reach out to me here in the Community.  I'll be glad to help you. Have a good one!
