For 2016, you should amend because you do get to deduct the moving expenses since they were essentially paid with taxable income, because your employer added them to Box 1 of your w-2. In 2017, you're entering the expenses but you will really only get a deduction for any amount over the code P amount. It may look like a deduction as far as your refund goes but what's really happening is your code P amount is being included in your taxable income UNTIL you enter your expenses. By entering them you see the tax owed or refund amount change in your favor because you've just confirmed the code amount was indeed nontaxable and the program is removing it from taxable income. Only the balance becomes a new deduction. I know this is confusing and I'm sorry.
