Beginning Balance in reconciliation window does not match statement
I started using QB Desktop for Mac in January. I set up my accounts correctly. All my opening balances matched my ending balances in the previous software. I have been reconciling the checking account monthly. It always balanced. I tried today to balance to the April statement and noticed that the beginning balance was off by $6,188.72. I followed the advice on other threads and ran the discrepancy report which showed nothing. I looked at the audit trail and found nothing. So I began looking all the way back to Jan 1. And when I ran the Previous Reconciliation report for January it showed a beginning balance that was wrong by $6,188.72. I was puzzled. I looked and looked and looked. Most recently I undid the Jan, Feb and March reconciliations thinking that if I started from scratch maybe the error would be gone. It is still there even though I can see in my register the correct starting balance. You can see this in the screen shot. I don't know what else to do. (Oh, I also verified my data--no problems found--and rebuilt the data but nothing changed.) What should I do?
