"year to date" Are you trying to use a paystub or do you have your W-2? Where are you seeing the amount?
Your employer just stopped withholding federal tax? Have a conversation and find out why. If your W-2 is wrong they need to issue a corrected one for you. If they really did not withhold tax, then right now --sorry--but it is what it is.. If you did not have tax withheld then it is possible that you owe now.
Maybe you need to give the employer a new W-4 to have them withhold more.
