Thank you so much for your response! I understand how it could happen. I was not aware of the Audit log, which I checked out. I can't find anything on the log that suggests I did something to that account. It would have to be done to the dates prior to me reconciling that month, because it was all in balance at one time. When I look at the Discover register now, there is a whole date range of entries not there, but the log does not show that I altered the entries. ???

I still don't understand, and I am at a loss as to how to continue. I have unreconciled my last account, but the balance is still off. I don't know how far back the mistake is, and I can't find it anywhere.
