I appreciate you for coming back to the thread to add additional confirmation about your concern, 1 Learning. With this, I'll be sharing information on how reconciling past entries works. Then, ensure that you'll be routed to the right person to assist you further on this matter.

Once you start reconciling past ot previous transactions, the whole current reconciliation statement will be inaccurate. That said, it causes your account differences like ending and beginning balances. However, once you have already performed accurately in reconciling your monthly reconciliation, the entries that need to reconcile in the next years will match your bank and credit card statements and ensure that there are no discrepancies.

To ensure your records are in shipshape, I suggest consulting an accountant before performing the process of reconciling past transactions. They can provide suggestions on how to properly handle those entries to avoid any data issues.
