I want to ensure you can undo your reconciliation, julie. I'd be glad to show you how.
In QuickBooks Online, we can manually remove the transactions one at a time on the Bank Register page. Doing so helps us unreconcile them without the help of an accountant.
Here's how:
Go to the Transactions menu and then select Chart of Accounts.
Find the account and click View register.
To help you focus on this task, 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.
Tick the box and keep clicking it until it's blank. It removes the transaction from the reconciliation.
Hit Save. Then, repeat the process to remove the other entries.
