Hello, I need help filing my taxes. When file your W-2’s do you file all 4 boxes or you just file 1 box from each job you have ?

When you use Turbo Tax program, you fill out your W-2's on the program exactly as it is on your "real" W-2 form. All boxes must be filled out for Federal and State.

Don't understand your question.  You enter each W2 separately.  You enter all the boxes on each W2 form.  Some employers will send you up to 4 copies of your W2.  Just enter 1 W2 copy for each employer.

 If one employer sent you 2 W2s with different info on them then ask about that.

You have to file all your income on the same tax return.
