Hello there, @Joycee.

Let me walk you through the steps to fix the prior posting that @Anonymous advised.

This method uses a date other than the most recent reconciliation and does not require that you know the ending balance from the previous reconciliation. Here's how:

1. From the Banking menu, click Reconcile.
2. Select the account you need to reconcile.
3. In the Date of Statement field, enter an off cycle date within the statement period on which the transaction appeared.
4. In the Ending Balance field, enter $1.00 then click Continue.
5. In the Reconcile window, check off the deposit transactions that you are re-reconciling.
6. Take note of the Cleared Balance amount.
7. Click Modify to reopen the Begin Reconciliation window.
8. Copy the Cleared Balance into the Ending Balance field then click Continue.
9. Click the Reconcile Now button.

Here's an article for more detailed steps and information: Reconcile Previously Deleted and Re-entered Checking or Credit Card Transactions.

If you need assistance on how to make these corrections, you can consult your accountant. 

Please get back to me if you need further assistance with QuickBooks. You got me here to figure things out for you.
