I accidentally deleted a transaction that was already reconciled, how to undo that?

I'm here to help you restore your deleted reconciled transactions, Alina.

Deleting reconciled transactions will result in a discrepancy in your reconciliation. In QuickBooks Online, the option to undo the deleted transaction isn't possible. Hence, we need to re-create to correct it. To begin, let's check your audit log to review the deleted transaction for accuracy.

Here's how:

1. Proceed to the Gear icon, then Audit Log under Tools.
2. Select the appropriate user, date, and events in the Filter dropdown menu.
3. Look for the deleted transaction.
4. Hit View on the History column.
5. Re-create the transactions based on the details found in the Audit Log.
6. Make sure to change the reconciliation status in the register to "R " for Reconciled.
