Here's how I fixed the error when it happened to me without needed to talk to "support."

1. Go to the invoice and then go to the incorrect payment.
2. Uncheck the incorrect payment from the invoice and apply the incorrect payment as a credit to the customer’s account
3. Now the Invoice is open to receive a new payment.
4. Go to the bank screen where the correct deposit is and match it to the new payment. Now the invoice is correctly paid.
5. QBO won’t match the chargeback expense to the customer. It’s not recognized as part of the Customer Invoice, Payment, Deposit coding.
6. Create a journal entry that debit’s Accounts receivable with the customer name, and credit’s Ask My Accountant.
7. Go back to the customer account and match the journal entry to the account credit to zero it out.
8. Locate where the incorrect payment was coded. If it’s not in Undeposited Funds, then check the bank accounts
9. Change the journal entry to where the payment was coded to zero out the payment.
10. On the bank transaction list, select the incorrect deposit and the chargeback expense and exclude both.
