how can I amend w2 in quickbooks?

Hey, @jairo3. 

It's great to see a new face here in the Community! 

Depending on your payroll service and if the W-2s and W-3s have already been filed, either you can fix it or we’ll fix it for you.

Review this guide to get the steps you need based on which version of QuickBooks Payroll you have: Fix an incorrect W-2. 

I hope this helps. If you have any trouble along the way, don't hesitate to come back. Have a wonderful day!
