Get your taxes done using TurboTax

Turbo Tax does not seem to have any way to calculate California estimated taxes that I can find. The instructions say the program will offer to do that, but it does not. It was astoundingly obscure to find out how to get TT to calculate Federal estimated taxes. So how do you get Turbo Tax to actually do what it says it does automatically but does not do and does not seem to have any way to get it do? I get divide by 4 and fill out the state estimates but that's beside the point.
