Hi there, TJRSrim. 

I'd say the same thing if I don't get the right answer. Let me help you get your invoices paid.

We can pay an invoice by opening it, clicking on Receive Payment, and entering the details on the next page. You can also match a downloaded transaction to the invoice to mark it as paid or link an open credit to it, as ShiellaGraceA shared.

My question is, how did you record yours, and when you record an invoice payment now using the normal Receive payment process, what happens?

You can check out to this article for more information about Handle a customer credit or overpayment in QuickBooks Online. 

Thanks for dropping by. Please know that I'm just a comment away if you need further assistance. Have a great day.
