Was the refund check assigned to A/R?  It needs to be assigned to A/R if the overpayment was created by 'Receive payment' on the invoices.  Then, you should see both the overpayment (A/R credit) and the check issued (A/R debit) when you go to New > Receive payment.  Apply the overpayment to the refund check and you're all set.
