I can't find undo function key in the to undo bank reconciliation. in the action it just show me print only? please help

Hi there, 

If you need to make changes to your reconciliation, it's important that QuickBooks Online allows for this. Mistakes happen, and it's my goal to help you get things sorted out. Don't worry, I'll help explain how to undo your reconciliation.

If you're connected to an accountant in QuickBooks Online, your accountant can undo or delete completed reconciliations by following the steps in this article: Undo your client’s reconciliations with QuickBooks Online Accountant. Having your accountant complete these steps is the best way to undo a reconciliation, as they have access to the Undo tool you're referring to. If you're not connected to an accountant, you can find one in your area here: Find a ProAdvisor.

You may not need to do this and lose all your reconciliation work. Take a look at this article to see if you can avoid undoing your reconciliation: Avoid undoing a reconciliation.

If you're still in need of undoing a reconciliation, and you're not connected to an accounting professional with access to the Undo tool, here's what you'll do: Undo and remove transactions from reconciliations in QuickBooks Online.

If you have any other questions about this process, let me know. I'm here to help. 

Have a great day!
