Hi again, mjm0027.

I understand the importance of you being able to reconcile your accounts in QuickBooks Online.

Right now, the undo reconciliation feature is only available in QuickBooks Online Accountant. This is to prevent some admin users or master admin to mess up the books already reconciled.

With this said, I'd suggest reach out to your accountant to help you with the reconciliation. Since QuickBooks Online for Accountant has the ability to undo multiple reconciliations without manually editing individual transactions from within the register.

You can invite also your accountant, then from there they'd able to help you balance your books. You can forward them this article: Undo your client’s reconciliations with QuickBooks Online Accountant for guidance.

Please let me know if I can be of further assistance. I'm always here to offer additional assistance.
