Thanks for reaching out to us in the Community, @kevin-cota.

I'm here to share some information about the undoing reconciliations in QuickBooks.

Just to confirm, are you using QuickBooks Online Accountant (QBOA) version? If so, you have the option to undo a reconciliation. Here's how:

1. Go to the Gear icon at the top and pick Reconcile under Tools column.
2. On the Reconcile an account page, select History by account.
3. On the History by account page, click the Account and Report period to locate the reconciliation to undo.
4. Choose Undo on the Action column, then Yes.
5. In the final confirmation window, pick Undo and OK.

On the other hand, if you don't have this option, it's possible that you're not using QBOA. If that's the case, you need to manually edit each transaction to undo the reconciliation. Here's how:

1. Go back to the Gear icon at the top, then pick Chart of Accounts under Your Company column.
2. Locate the appropriate account for the transaction and select View Register on the Action column.
3. Identify the transaction to edit.
4. In the reconcile status column (indicated by a check mark), repeatedly click the top line of the transaction to change the status, then Save.

• C - Cleared.
• R - Reconciled.
• Blank - Not cleared or reconciled.
