Hello there, @stan2.
Thanks for reaching out to the Community. I can walk you through the steps for updating the W4 information.
What Payroll subscription are you using? Since you indicate Payments, I’m adding the steps for QuickBooks Online Payroll/QuickBooks Full Service Payroll (QBOP/QBFSP), Intuit Online Payroll/Intuit Full Service Payroll (IOP/IFSP) and QuickBooks Desktop Payroll (QBDT Payroll).
Here are articles that tackle more about this:
That should get you on the right track.
Let me know if this works out for you, I’m always ready to help. Have a good one!
