Finding an amount that is off from the actual bank account in funds

We just installed 2017 but the problem was before.  Is there a way to run a report to find a missing amount that is throwing my Funds Balance is off.  The  balance in checkbook  one day was off, but all transactions  in and out for the past year match and are correct.  Is there a way to search for it?

I actually have too much in timeslips by $185.
