You asked "Where did it ask you to change your password?" I don't remember where, and I don't know why, so I assumed this was Turbotax extra online security. In the meantime how do I see my 7 years of taxes at your site? I don't always carry over from the previous year and start a new session, but would that make a difference?

PS I was able to successfully do my tax after I originally sent this question in.
