These were distributions from a 401(k), not from an IRA, so the IRA/SEP/SIMPLE box must not be marked. I just reread your original post and what what I see there now doesn't make sense. Somehow I had the impression that $40,000 after-tax basis was rolled over to the Roth IRA. As I read it again, the original Form 1099-R is reporting a distribution of $70,000 of after-tax basis and $40,000 of pre-tax money. This disagrees sharply with your assertion that you had only $10,000 in after-tax basis. However, you said that the plan rolled over only $10,000 to the Roth IRA, so that agrees with having only $10,000 of after-tax basis. (Note that any gains on the $10,000 in the after-tax subaccount are pre-tax.) This all suggests that the original Form 1099-R should have $110,000 in box 1, $0 in box 2a and $10,000 in box 5, so the splitting of forms should be done to show $100,000 to the traditional IRA and $10,000 to the Roth IRA. The resulting taxable amount will be zero.
