After you file

Any other way? I'm not getting back to my return when I try the above method.

Instead I get:
It looks like your federal return can't be amended right now

This is a nationwide delay for all returns like yours, no matter who's preparing them.
You're going to have to wait until the tax form for amending a return (Form 1040X) is ready for processing.
Form 1040X will be ready on 03/07/2019.
Email me when this form is ready
Why isn't Form 1040X ready for processing?
