I reconciled November and realized I made an error in a payment to a contractor which I log as an expense after the fact. When I realized the overpayment error, I adjusted the expense. Now, I'm trying to go in to reconcile December and I'm getting an error that I cannot reconcile because my account isn't ready to reconcile yet, since my beginning balance is now off by the amount I corrected. How do I adjust the ending balance in November, so that I can proceed to reconcile December?
