I did a conversion from a traditional IRA to a Roth this year. When I enter the distribution amount from the traditional IRA, my tax bill goes up.  Then later, TurboTax asked if I contributed to a Roth IRA. I entered the same amount there, and my tax bill went up again. Seems to me like I'm being taxed on the amount twice.

So my question is whether I need to enter it twice, or if when entering the 1099-R, I indicate (as asked) the amount of the distribution that was converted to a Roth, is that sufficient?
