I have a related question. I did a partial conversion from a traditional IRA with a non-deductible basis in the 4th qtr. I will need to make an estimated payment to avoid a penalty. I think the taxable amount is conversion amount minus (total basis divided by total value of all IRAs)(conversion amount). TTO has my carry over basis and the other amounts, but I don't see anywhere that it reduced the taxable amount. I know the 1099R will have taxable amount not determined, so how do I figure the taxable amount of the conversion, or make TTO do it for me?
