If your W-4 continues not calculating its federal withholding after using each of my colleague's recommended troubleshooting processes, I'd recommend getting in touch with our Customer Care team. They'll be able to pull up the account in a secure environment, conduct further research, and create an investigation ticket if necessary.
 

They can be reached while using QuickBooks.
 

Here's how:

1. In your top menu bar, go to Help, then QuickBooks Desktop Help.
2. Click Contact Us.
   
3. Enter a brief description of the issue in our Ask a question (or tell us what's wrong) field.
   
4. Press Continue.
   
5. Select We’ll contact you for callbacks or Message Us to start an instant messaging session.

Be sure to review their support hours so you'll know when agents are available.
 

Please feel more than welcome in sending a reply if there's any questions. Have a wonderful Monday!
