I am not entirely sure. When the AGI from last year does show up (which is about 1/3 of the time I go through the file continue tree... it shows up as zero. But I have no idea if that was the value entered on the previous attempt to file. In addition, my turbo tax does open with the option to 'fix taxes.' I guess the usual home page with the 'let's amend' option, and when I click that I'm simply back in the amended return.
