Again "out of whack" is hard to diagnose in a public forum ... the program does math calculations very well 99.9% of the time ... the variable would be the user making an input error 99.9% of the time or just not understanding the situation.
So put the returns side by side ... what increased the taxes? Were you self employed that year ? Did you have to pay back some or all of the Obamacare credit ? Was it a simply data entry error on the W-2 for the income or withholding ? And why didn't you question this 2 years ago?
