Thanks for your prompt response, @azim - Vancovuer BC.

Right now, the option to delete the reconciliation reports is unavailable. Alternatively, we can manually undo each transaction in that reconciliation report.

This way, the reconciled transactions will be removed from the completed reconciliation.

Here’s how:

1. Select the Gear icon and then select Chart of Accounts.
2. Click on the account in question.
3. From the Action column, select View Register (or Account History).
4. Select the transaction to edit.
5. In the reconcile status column (indicated by a checkmark), repeatedly click on the box until it changes from "R" to blank.
6. Select Save.

For more details about unreconciling and removing an individual transaction from a completed reconciliation, you can refer to this article: Undo and remove transactions from reconciliations in QuickBooks Online.
