If you are amending a 2020 tax return, that can be e-filed. If you amending a return from an earlier year, then you will need to print the return and mail it. Here are detailed amend directions. Select the year that you wish to amend and follow the directions for that year.
Keep in mind: You have 3 years from the date you filed your return or 2 years after you paid the tax due (whichever is later) to file an amendment.
