How to undue a reconciliation - MY END STATEMENT DATE SHOULD BE SEPT 30 2019 BUT SAYS 2/18/2020 HOW DO I FIX THIS?

Hi there, @user53081.

Thanks for visiting the Community. I can help you undo your reconciliation so you can update the ending date in QuickBooks to match it with your bank statement. Here's how: 

1. In the Accounting tab on the left panel, select Chart of Accounts. 
2. Locate the bank you’re working on, then click View register in the Action column. 
3. Click the Funnel icon to filter the date, then choose Apply.
4. Locate and click the transaction, one at a time.
5. Between the Deposit and Balance (USD) columns, keep clicking the R field until the status changes to a blank (unreconciled) or C (cleared).
6. Click Save.

Once done, enter the correct statement ending date. Here's how: 

1. In the Reconcile page, select the account you’re working on.
2. Click Start reconciling, then, go to the Edit info tab and refer to your bank statement to re-enter the correct Ending balance and the Ending date.
3. Click Save. 

You can now start and finish your reconciliation. Refer to this help article for more information: Undo individual transactions on a reconciliation. It has a step-by-step guide to help you unreconcile a transaction.
