Apparently the entire procedure to E-file amended returns has changed since yesterday. One of those yellow highlight bars announcing that would have been nice.

Is anyone else having difficulty e-filing the 1040X now? Followed all the new steps, but I keep getting the message that a return has already been filed with that SS# and I can not get it to e-file.

I am using the file listed under the Amended return column, Marked for e-file, but no luck.
