I'm in a slightly different situation than the others here.  I use QB online for our homeowners association and send out invoices for amounts due the association.  I took over in 2022 and one member had an overpayment, so I told them to underpay an invoice in 2023. I'm not sure how I should have handled it, but now I have an unpaid balance on the invoice in 2023 (and I don't want to go back and change 2022). Now, I'd like to write off or make a journal entry to eliminate the balance on that invoice with the corresponding credit/debit going to the expense account for that item.  It isn't a bad debt, so I don't want to create a bad debt account.  It's just an accounting mistake to correct, so it doesn't carry over to 2024.  It's a small amount.  

Thanks you
