Appreciate the info, David.
1) It does seem that I'll have to file for 2017 and 2018 tax amendments once I get the 1099R forms next year for any interest earnings corresponding to the contributions made in 2017 and 2018? Even though they are 2020 forms, those earnings will count towards 2017 and 2018. If I am understanding you correctly, will the 2020 1099-R forms be used in 3 places: 2020 tax filing, amending 2017 and 2018 taxes with any interest earnings even though I will pay the fine in 2019 tax year, as you suggested?
2) For 2017 and 2018 excess roth for 2019 filing, I am only seeing this: 'Enter your Excess Roth IRA Contributions for Prior Years'. There is only one place to cumulatively add all past years excess contributions instead of each year? Am I missing something? Any instructions on getting turbotax to enter and accept each past year's excess? I'd think this is needed to the accurate calculation of 6% penalty etc?
