Welcome to the Community, smbrooks.
You've reached the right place for assistance. I want to make sure you're able to record this payment in your QuickBooks Desktop account.
There are a few different reasons as to why you would be seeing that error message. For example, the invoice is already partially or fully paid in QuickBooks. Here's how to get that fixed:
1. Find the invoice for the payment that generates the error.
2. Void or unapply any payments against the invoice so the full balance is due.
3. Close and re-open Merchant Service Deposits.
4. The payment will now record.
The following article provides additional info and troubleshooting steps to get this issue resolved: Error in Merchant Deposits "A payment you are trying to download can not be matched or recorded"
Please give this a try and let me know how things look afterward. I'll be here if you have any other questions.
