You can undo the reconciliation, ronc1.
The Undo option for a reconciled period is only available in QuickBooks Online Accountant. I'd recommend inviting your accountant to your company, and let them undo the reconciliation period at once.
- Click the Gear icon in the upper-right corner, and select Manage Users.
- Go to the Accounting firms tab, and click the Invite button.
- Enter the accountant's information.
- Click Save.
- Let your accountant undo the entire reconciliation.
Otherwise, you'll need to undo the reconciled transactions one at a time. You can use this article for reference: How to Unreconcile a Transaction or Undo a Reconciliation.
Check this article for future reference: Fix issues during a reconciliation in QuickBooks Online.
