Good to see you here in the Community, @Nicolet31. I'll lay down a few steps to fix issues with transactions you've reconciled in the past.
Since you need to modify those transactions, you'll want to do a mini-reconciliation that uses an "off-cycle" to make corrections. However, this needs professional advice from your accountant to ensure the best process to handle these amounts.
Here's how:
- From the Banking menu, select Reconcile.
- Choose the bank account with the transactions you need to reconcile.
- In the Date of Statement field, enter the date for an "off-cycle reconciliation." This can be any date between your last reconciliation and the next scheduled one.
- In the Ending Balance field, enter the balance of your last successful reconciliation. Then select Continue.
- From the Reconcile window, check off the transactions you are fixing and re-reconciling.
- Ensure the Difference field shows $0.00, then select Reconcile Now.
From there, QuickBooks asks if you want to Create a Payment Check or a Bill to Pay Later. You can follow this article with a detailed process: Reconcile previously deleted and re-entered checking or credit card transactions.
We have various reports in QuickBooks Desktop where you can review your past reconciliations: Get reports for previous reconciliations, which gives you details that can help you find discrepancies and other issues.
