I have a traditional IRA with a non-deductible basis, but did not make a non-deductible contribution in 2023. I also have an inherited IRA with taxable RMD and 1099-R for 2023. Form 8606-T line 6 sums across all IRAs in order to adjust how much of the RMD is not taxable and then to adjust the remaining non-deductible basis.
Things worked as expected for 2022, but not for 2023. First I can't get 8606-T to be added to the 2023 return without a non-deductible contribution (IRA Contribution Worksheet, line 1), but that worked last year. I can get 8606-T to be added when I say there was $1 of non-deductible contributions in 2023, but even then I can't get it to bring over the value for 8606-T line 6 (IRA Information Worksheet, part IV, line 18) and do the calculations. Also, I can't get it to fill in 8606-T line 7 from the 1099-R.
Suggestions?
