Let me elaborate some details on how you can undo a previous reconciliation, Treasurer.
You'll have to make sure to undo the previous reconciliation before you delete a transaction so QuickBooks won't prompt you the message. Please know that you can only undo a reconciled transactions one a time. To do so, follow the steps below:
- Go to the Accounting menu. Then select Chart of Accounts.
- Find the account and select View register.
- You can filter the register to only include the last 60 days of transactions.
- Review the check column. If the transaction is reconciled, you’ll see an “R.”
- Select the box and keep clicking it until it's blank. It removes the transaction from the reconciliation.
- Click Save. Then close your register.
Once done, you can now delete the transaction. I've also added here an article that will help you in case you encounter reconciliation issues: Fix issues when you're reconciling accounts.
