dmertz: Once again, you've been very helpful and have explained the situation very well. Thanks for taking the time to reply! One question remains: Should the distributions from inherited IRAs be included in line 7 of 2020 Form 8606 (and in line 11 of Form 5329 - year 2015-"Traditional IRA distributions included in income")? Turbo Tax includes these distributions in these locations from the 1099 info. As for the 2020 Form 8606, It doesn't seem right that the inherited IRA distributions should impact one's traditional IRA basis, nor should there be a non-taxable portion of the inherited IRA distribution based on a conversion of a portion of one's traditional IRA into a Roth IRA. I hope I've made this question clear.
