Retirement tax questions

If what these Turbo Tax "experts" are saying is true, then they have had defective software for over the last decade, since all of my returns for the last 10-12 years have included state retirement 1099-Rs with code 2 with the Turbo Tax software indicating and applying it as not taxable in the State of MS.  Their negligence has the potential to create a major liability for a lot of people.  Are there any attorneys out there?  A class action may need to be started.
