Thanks for your quick, and informative response to my question! Please see my comments (and additional questions) below.
"You may see a follow-up question about tracking non-deductible contributions in your IRA after you have entered the Form 1099-R reporting the distribution from the Traditional IRA (which was converted to the Roth IRA). "
-- I only get Qs about non-deductible contributions, if I enter an amount in box 9b for 2024's 1099-R form; which I'm reluctant to do since it's blank on the actual form.
"As you get started in that section, check the box that you have a Traditional IRA and go through the screens until you see a question about 'any non-deductible contributions' to your IRA. Â Check 'yes' and then enter the total basis of the account as of the end of the year. Â Remember, this is only asking for the contributions that were made, not the total value of the IRA. "
-- This is where it gets complicated (and confusing?). I have made non-deductible traditional IRA contributions (tracked on Form 8606, and in TurboTax) in prior years; but want to "keep" those until I start taking RMDs at age 73. Besides, these were after-tax contributions to a 401k (that was rolled into a Rollover IRA) - I have a 1099-R from 2018 documenting this. The only way I see in TurboTax to reduce taxes on this year's partial distribution from the Rollover IRA (and converted to a Roth), is to enter these after-tax (and therefore non-taxable) 401k contributions in box 9b (documented by supporting details; the 1099-R from 2018 maybe). But having a "mis-matched" 1099-R for 2024 (again, box 9b is blank) would be a red flag to IRS - do you agree?
-- Btw, I plan to do this (Roth conversions from this Rollover IRA) several more times; so, I'd like to do it in a way that's repeatable (and correct, obviously).
