Get your taxes done using TurboTax

I'm totally lost.  When you say "TurboTax Premium if a totally different product than Home and Business", do you mean that I can't upgrade from existing Premium version to Home & Business?  I thought you would be allowed to upgrade from existing Premium version to Home & Business.  My question was: how much extra would I pay doing the upgrade.

 

Can Premium do Schedule C and handle loss carried forward from previous years?
