Hi there, qwerty007.
To get the correct withholding, you'll have to override the Federal Income Tax in the Run Payroll section. Then, enter the withholding amount calculated based on supplemental tax rates (22% or 37%).
You can find more details in this article under QuickBooks Online Payroll Enhanced: Create final employee paychecks.
