If I use Turbo Tax am I missing something?
Nope. TurboTax walks you thru with a serious of questions yes or no. You say yes it then ask for more details. You say no on to the next. You have the option to revisit any section afterward or even during the process.
You even have the option to see the forms as TT has filled out and change them if you want.
JettaKnight being an engineer and analytical i suspect would enjoy building a lego set using the instruction book that comes with it. She would find it peaceful just like i do when i build lego sets and or do my taxes.
