First, make sure you really need to amend and that your 2020 return was accepted in TurboTax Online or paper-filed through the mail. You can't amend a return that hasn't been filed yet.
IRS Form 1040-X (amend your return) will be ready on March 25, 2021. Sign up for email notification and we'll let you know when the most current form is available.
