how do you unreconcile a register ?

Hi there, @islandtile2020. I’ll walk you through the steps on how to unreconcile your register.

You can manually undo reconciliation by going to the Chart of accounts.

Here's how:

1. Go to All apps on the left menu and select Accounting.
2. Click on Chart of Accounts.
3. Find the account where the transaction is recorded, then select View register.
4. Look for the transaction in the list. If it's reconciled, you'll see an "R" in the checkmark column.
5. Click on the transaction and in the checkmark column, click the box with the "R" until it clears (the box will turn blank).
6. Select Save to update the transaction.

If you are referring to undo the entire reconciliation, I highly recommend that you invite your accountant in that process for proper guidance. Here's an article to guide you through the process: Undo a client's entire reconciliation in QuickBooks Online Accountant.
