After you file

Thank you! Will Turbo tax allows for e-filing tax amendment for 2020? It doesn't seem work for me as Turbo tax says that "e-file season ends in 4/15/2021"; however, irs says "If you need to amend your 2019, 2020 and 2021 Forms 1040 or 1040-SR you can now file the Form 1040-X, Amended U.S. Individual Income Tax Return electronically using available tax software products".
