Hi Jen,
Could you please give me some more information on what you mean by catch up a transaction?
If I am understanding correctly it sounds like you want to adjust the opening balance of your bank account so that you can continue forth with the bank reconciliation.... and while you could definitely do a transaction or a journal entry to fix the balance, I highly recommend checking with your accountant and see what they recommend first because it could cause other problems down the road. I hope this helps.
