Proper treatment of lost refund check for duplicate payment on invoice

[HeritageArts]

I have reviewed this old thread, and while helpful, it does not exactly fit my situation:

Overpaid invoice refunded back to client

I have had an invoice paid twice i.e. invoice was for 75.00 but paid twice, so now shows as -75.00 (overpaid). I have now sent the funds back to the client. How can I correctly reflect this in manager so that the overpaid amount deducts from the invoice. (I would be inclined to show the expense as spend money and reflect this way but this doesn’t reduce the overpaid amount on the invoice)

A customer paid an invoice twice, and both payments were deposited. They wanted a refund, not a credit against future invoices. I issued a check and posted it against accounts receivable for that customer.

The check was never deposited, and it is apparently lost. I want to cancel payment on it at the bank and void it. Then I need to reissue the check.

Is it appropriate for me to follow the approach of the referenced thread to create a new “customer overpayment” liability account, change the duplicate deposit from accounts receivable to customer overpayment, and then simply change the first refund transaction to the new check number and change its posting from customer’s accounts receivable to the new customer overpayment account?

As the cheque was never deposited, just re-bank (Receive Money) the cheque back to the Customers account - this will enable the original cheque to be matched off against in the bank reconciliation and then re-issue a new cheque via Spend Money
