Bests & Worsts Reviews from Amazon

I have been using Turbo Tax for 20 plus years. I ordered Premier Edition for 2016 this year. I found several errors in the program, in particular in the California State program. First of all, in 540 form, which is the first page of California Income Tax Return, for my personal 2 exemptions, it states 2 X 109 = 222. Even the first grade student knows that 2 X 109 = 218. Secondly, the federal form does not transfer all the information to California forms. In particular, for Federal I have ten 6252 forms (installment sales). It transfers only to 9 California 3805E forms. That is the maximum no. of forms available for the State. When you use federal form 4797 page 2 to calculate depreciation, for California it calculates tax on the installment sale as well as on the full price of the property. Thus, you would end up paying much more income tax than what you owe. I know with my experience that most of the filers plug in the numbers, relax and wait for the results. In my case, I have been able to detect these errors, since I am a graduate with Math. major. I attempted to contact customer service. On three occasions, the rep. hung upon me. I was not able to contact any one at all.
