Same situation, same thing happened with me. Went from having a refund to owing about $1900. TurboTax Deluxe didn't catch this issue. Quite an unpleasant experience. My only resolution was to pay, of course, and to write this answer, that I share your pain. My 5-star opinion of TurboTax is now a 2-star. I'll be looking for alternative software next tax season and I'm not recommending TurboTax to any friends from now on.
