Federal and California taxes incorrectly calculated by TurboTax (desktop) - should TurboTax be responsible for the errors?

I got back some letters from IRS and State of California Franchise Tax Board recently.

 

On Federal, the letter said some penalty was incorrectly calculated so they sent a check back.

 

On California, TurboTax determined I qualify for excess SDI and FTB said that is not correct, so my refund was reduced by that amount. Also, most likely because of that, the refund was not directly deposited in my account. 

 

I am wondering why, despite so many checks in the TurboTax desktop step-by-step, that both of those were incorrect. What is the guarantee that the product offers and besides not choosing TurboTax next year, what else do I have at my disposal for these mistakes and how does TurboTax restore trust in their product?
