Amended returns cannot be e-filed. If you have prepared an amended return you have to print, sign and mail it. However, the IRS is not even opening mailed returns at this time; if you mail it soon it will end up sitting in a pile of unopened mail in a trailer. Sometime later in the year (we do not yet have a date) the IRS will start to allow e-filing of amended returns. You might want to just wait for that. You have three years to amend a return.
