You mention - "when it asks for prior year non deductible contributions". I will assume you are referring to the screen titled "Let's Find Your IRA Basis" where it mentions looking at your Form 8606.
This is a bit confusing because I don't have a Form 8606 from a previous year (as i didn't contribute anything until 2020). Then the question asks "Total Basis as of December 31, 2019" - technically speaking my cost basis was zero as of that date, as I didn't make a contribution until 2020. But maybe from a tax year perspective it still counts regardless of the exact timing?
Regardless, I did add 6K here to account for 2019 basis, and this did negate my tax burden for this activity.
I appreciate the assistance!
