All the information should be saved on some sort of "TurboTax account" or something I would imagine. I do mine through H&R Block online and was able to retrieve last years info through the online "account." I guess if you could get TT installed on your computer and have the account information, you could access it and get your information you need. I've never done TT, so I don't really know how it works.
As for #3, you could look at it that way, lolol. Later, QD.
