How do I adjust the source deduction liability when multiple duplicate paycheques are created in prior months?

It’s great to see you in the Online Community, Lisa Marshall.

Correcting the payroll data requires viewing of transactions. The process requires in-depth troubleshooting steps and account verification.

We’re unable to perform them here in the Community for the company's safety. I recommend contacting our QBO Payroll Team for further assistance.

They'll ask company details to view the account and use their tools to adjust the deduction liability. You can reach them by following these steps.

1. Go to the Help menu located in the upper-right hand.
2. Scroll down and click on the Contact Us link.
3. Type in the issue/topic in the field box.
4. Click on the Let’s talk button.
5. Choose a way to connect with us: Chat or Get a callback.

Your payroll records should show the correct information. 

Keep me posted on how things go after them. I’ll be right here if you need further assistance.
