Thank you for a very clear (non-generic) reply! I can't believe that such a big company like TurboTax would not have the ability to store your tax information to your TurboTax account especially since it seems like people that do their taxes through TurboTax Online can do that (or is that not the case?). I also can't believe that the latest software version cannot open previous years taxes, requiring us to save the installation file of TurboTax of previous years. These seem like basic fundamental functions such an advanced software should have. No backwards compatibility? Seriously? Maybe TurboTax is not a very good long term tax solution after all.
