Take action ! Ammended return ... whats this?

I have no idea what you're talking about with "take action". But an amended return can not be e-filed if that's what you're trying to do. (The IRS says so.) You have print, sign and mail it to the IRS.

The IRS has a fax number. It may save time but please check. The # is [phone number removed] it on a notice I received for a 2016 and 2017 tax return.
