I agree (on restrictive). I spent over 3 hrs trying to get the return amended and forms to populate properly only to have TurboTax not save the 1040X form apparently because I didn't use the "easy-step" and just opened the 1040X form. AND then to add insult to injury I couldn't e-file the Amended return for the reason you found, "closed for the season" - TOTALLY unacceptable! Should be able to e-file an amended return for up to 2 years (especially if it was e-filed and accepted originally). I have to say I'm getting more and more disappointed with TurboTax user interface, testing, and quality of the software.
