I have been using Turbo Tax for 10 yrs and I have some pretty complicated returns some years and TT has never screwed me. I know people who use tax break and H&R software and had issue especially with stocks. It seem like many companies today are offering online tax return for free, you have to ask, how can they do it for free and how are they making money, probably selling your information. Plus you just put your SS and other important tax information online where those smart hackers could probably get access to it.
I tell people do not post your personal information especially tax information online. Why, when real thieve break into your home and steal your stuff one thing they try and find is old tax returns, then sell that information to identity thieves, since everything they need is contain in your tax return.
Be smart and protect your information
