I had some one reconcile my bank account within zoho books, and I noticed I have an invoice outstanding that was paid in May 2022, what is the best way of removing the transaction the bookkeeper added so I can appropriately put it against the customer so I don't have outstanding AR?

Also, if I have AR that are years old how do I remove them the right way if they were paid and just incorrectly reconciled years ago?

I inherited a mess and am not a bookkeeper/accountant.
