Hi All - first post here and new to the trade.

As part of a 12 month catch-up, I am trying to do a reconciliation for Jan 2023, and the beginning balance is off. A check from 2021 was deleted in 2023. Customer has no idea what check was for or how that happened, seems previous bookkeeper did it. What type of adjustment can I make so that I can move on with the reconciliation? TIA

P.S. if there is another post that discussed this you can just send me the link.
