I'll help you correct this transaction so you can continue to run your business, @SuzanaH.

Allow me to share some information first on how to manage payment in QuickBooks Online.

There are two options to record sales transactions in QuickBooks, and it depends on when you receive the payment. You can use the Invoice and then Receive Payment for a deferred. However, you’ll want to use the Sales receipt once it’s immediate.

When you used the Received payment option in QuickBooks, you should match it directly to your bank transactions. This way, we can avoid double-counted income. You can delete the deposit and Sales receipt you made to correct it. Here’s how:

1. Go to the Magnifying icon and select the deposit. You can select the Advanced Search to locate the event easily.
2. Click More at the bottom and choose Delete.
3. Press Yes after.
   

Once done, go back to the Banking page then used the Find match option to match them in the program. You can check this article on how to add and match downloaded banking transactions for your reference.
