Get your taxes done using TurboTax

Dana, thanks for the detailed explanation; is there a reason/logic behinds that one pays tax for 2020 excess contribution on 2020 tax year (in 2021 april) while pays tax for 2020 earning from excess contribution on 2021 tax year ( in 2022 april)?  Why not pay both on 2020 tax year in 2021 april?
