I e-filed my 2020 tax return on 09/23/2021 (and I already got my refund), and now I need to amend my 2020 tax return for additional tax credit, but I cannot find "Amend a filed return" menu selection from my TurboTax Premier 2020 (Mac download version) software. Today's date is 11/17/2021. I check on the IRS website, the 2020 1040X form is available since July 2021. Can someone help me with how to initiate the amendment process within the TurboTax? I really appreciate it.
