Retirement tax questions

I understand what Critter-3 is saying, but I don't think it is very practical.  In my early years I did my taxes on the paper forms, partly because I didn't want anyone else's errors getting into my tax forms.  But once I had more money coming in and I got into the stock market and bought a second house that I used as a rental, the complexities of the tax code went way beyond my capabilities.  I had to get help and I chose TT.  For many years it has served me fairly well.  But lately they seem to be getting sloppy with the basics.  In this I am in agreement with Schwinkley.  TT loves to say how accurate they are, but I don't think they back it with a guarantee to pay any penalties that occur due to errors in their code, or do they?  If we cannot trust them with the basic calculations, ones that are so blatant, that as I said previously, I caught it on a very simply tax return; then how can we trust them with the calculations that we have no idea what the results should be?  TT had better up its game going forward because there are other tax preparation s/w systems out there, and also 97,000 more IRS agents.
