Very old reconciled checks showing unreconciled

Revised…...Checks and deposits. A deposit from 2025 just appeared when I went to reconcile August. So frustrating!

To resolve past transactions reappearing without re-doing years of reconciliations, you'll have to determine whether the items are duplicate entries or modified historical records. When QuickBooks Online detects previously reconciled transaction was edited, deleted, or un-reconciled, an alert line will appear below your beginning balance. Click the blue We can help you fix it link.

The Reconciliation Discrepancy Report opens automatically, displaying a list of altered transactions along with the original and current amounts. You can follow these steps to review and fix each change:
 

1. Navigate to the What happened column to see what changed, when, and who changed it.
2. Select Review in tray. For more details, click the dropdown next to it, then View History.
3. Follow the suggested fix in the tray, or make your own correction based on your records.

For additional reference in correcting the discrepancy, you can refer to your bank statements. Check your account register balance, it should match your bank statement balance without altering historical reconciled totals.

Once the system suggests to reconcile an individual transaction, you can mark it as R in the register, or reconcile the account again using the same ending date and ending balance as your last reconciliation. Both will correct the beginning balance, but only reconciling again records the change on a reconciliation report.

If they are indeed duplicates, you can delete them. Here's how:
 

1. Go to All apps and select Chart of accounts.
2. Find the bank or credit card account where the duplicate entries appear, and click View register. 
3. Scroll through the register or use the filter tools to find the duplicate transaction.  
4. Click on the transaction to expand its details, then select Delete.
5. Click Yes when prompted to confirm the removal.
