How can i remove a reconcile of a months band transaction that's been submitted in error

I've got all the steps to help you undo a bank reconciliation in QuickBooks Online (QBO), Ben. 

You can only unreconcile a transaction one at a time. If you need to start over, I recommend contacting your accountant. They can undo the entire period at once using QuickBooks Online Accountant. You can invite them by following these steps:

1. From the Cog Wheel, select Manage Users.
2. Go to the Accounting firms tab, and click the Invite button.
3. Enter the accountant's information.
4. Click Save.
5. Let your accountant undo the entire reconciliation.

 If you want to do it yourself, follow these processes to undo reconciled transactions one at a time:

1. From the Transactions menu, choose Chart of Accounts.
2. Find the account and select View register.
3. To help you focus on this task, filter the register to only include the last 60 days of transactions.
4. Review the check column. If the transaction is reconciled, you’ll see an “R.”
   
   
    
5. Tap the box and keep clicking it until it's blank. Doing so will remove the transaction from being reconciled.
6. Press Save. Then close your register.
