Let us know if you made and kept track of any nondeductible contributions to Aaron's traditional IRA from 2021 or prior years? HOW TO ANSWER THIS?
This is not part of your tax return filing. So it doesn't matter how you answer it. It's an extra feature of the software. TT will keep track of your contributions for you. The info will be transferred to the next year, each year you use TT. Answer no, if you are unable to input (you do not have records) data from previous years.
