Heads-Up one other issue I had with my ROTH conversion in Turbotax that you may want to watch out for.
I did my conversion in Q3 last year sending in large pre-payments to both Federal & State in Q3, and even though I have a refund coming, it still calculated that I had a penalty for "under-payment". Federal and TT assume equal tax pre-payments throughout the year based on your YEAR-END total tax due, so it calculates (erroneously) that I have under-payment penalties for Q1 & Q2.
I understand (from the link at the end of this post) that "I can go to Federal Taxes tab or Personal tab, under Other Tax Situations and select Start by the Underpayment Penalties. You will answer a series of questions that may reduce or eliminate the penalty." (reference form 2210, i.e. posting pre-payments withheld or made Qtr-by-qtr). I haven't done this yet - I just figured out what was happening.
