Can you edit a completed payroll run in QB online?

It's good to see you here in the Community, @mmarchand.

Editing a completed payroll is done via payroll correction. Thus, I encourage reaching out to our QuickBooks Payroll Team to help you void or delete the processed payroll and recreate it.

To reach them, you can follow the steps below:

1. Sign in to your QuickBooks Online account.
2. Click the Help button.
3. In the QuickBooks Assistance chatbox, select Talk to a human and choose I still need a human.
4. Select Contact Us.
