Get your taxes done using TurboTax

if you do the paper 1040-X, you lose the e-File option.

 

As I understand it, for TurboTax Online users, you are out of luck.

Support can't change the software and can only confirm what has been posted here before about this situation.

 

with CD/download program, you can make manual edits.

It's not clear if doing that would also shut off the e-File  option.
