Actually I have to say that this is one area that TurboTax needs to substantially upgrade. Everything else I've done has been incredibly user-friendly -- just answer the questions asked by the program, copy the relevant numbers from the forms, and TurboTax will do the calculations. For community property, TurboTax essentially says, "If you're married filing separately and live in a community property state, read the relevant IRS publications, figure out which parts of your income and deductions are community property, then figure out how to do the calculations, then finally enter the results of your calculations as an addition adjustment or subtraction adjustment. Just don't expect us to help you do any of this."
