I am in the same boat, usually get $3k back, now owe $10. It was driving me crazy for hours! It showed a reduction of about $15k in federal deductions when you click on why do I owe. But it shows 2017-2018 as being relatively the same at review. Reviewed everything, and upon relooking at mortgage interest paid, a window pops up saying that the law giving you credit for mortgage interest paid is UNDER REVIEW. And that it may affect your return! Lets hope so, I think that is the difference being seen, we are not actually getting that deduction for mortgage interest yet. Saved and will review later...fingers crossed that's the problem
