Basic inadequacies in tax software -- why?

Every year I seem to stumble upon a basic in inadequacy in either TaxCut or TurboTax. By this I mean screens where their programmers appeared to just throw up their arms and say "ahh, to heck with it, just make the customer do it." This year's examples (so far) are:

1. If I paid AMT last year, TaxCut can't or won't compute what part of my state refund is taxable. See screen shot at:

   In my opinion there is noexcuse for this screen -- I did both returns with TaxCutlast year and imported the data so it has all the datanecessary to do this computation, so why can't it computethis for me?
2. When doing my state tax form, TaxCut required me to manually enter IRA distributions received. Even though they are already entered on my federal form and the state program supposedly imports data from the federal forms. This year I'm experiencing these annoyances with TaxCut. But when I used to use Turbotax, it had just as many annoyances. Why can't these programs do these basic functions?
