All of the answers from a Quick books team member have been inadequate and do not actually answer the question that literally everyone has been asking. I am going to attempt to ask again and hopefully get an actual answer. 

My employee has written $4000.00 down on his W4 as his withholding per the instructions on the worksheet. 
When I enter $4000.00 into the box titled "Claim Dependents" zero income taxes are withheld.
We know that with the prior form that would have been entered as as 2 and income tax would be withheld.

How exactly do we enter their W4 information into Quickbooks so that it is accurate and properly calculating their with-holdings?
Please do not instruct me to run a payroll update, that is not the issue.
Please do not instruct me to reach out to a CPA as that will not be helpful.
We all need to know HOW to enter the information into your software.
