unknown outstanding withdrawals

SOLVED

I just noticed on this month's bank reconciliation that there is a -2928.48 outstanding withdrawals showing on the bank reconciliation screen.  However, there are no outstandings to clear.  I only caught this as there happened to be no outstandings to clear and no new transactions entered yet for the next month so I don't know where this amount came from.  When I pull up an account reconciliation report it shows no outstanding withdrawals on it but this amount is the difference between the bank and the general ledger.  I am wondering if this was as a result of something the previous bookkeeper did as she made a huge mess of the file as she was not an actual bookkeeper and didn't know what she was doing.  How can I go about clearing this amount or at least finding out where this amount came from so I can perhaps reverse it somehow or make some adjustment.
