After you file

One last question (I hope).  Do I do this in TurboTax 2021 or 2020?  The contribution was made in 2020, but I recharacterized it in 2021, before I filed my taxes for 2020.  I ask this because TurboTax 2021 was telling me that I may need to amend my 2020 returns because of the recharacterization.
