1. don't care that Turbotax will not keep any of your records on file,
2. need absolutely no help at all- not even any clarification on terms,
3. are willing to print up your returns when completed and mail them yourself,
4. own absolutely nothing but are just filling out a 1040EZ form for your taxes, well, then...
the Turbotax "free" version may be for you. If you are the kind of person who "gets excited to read a disclaimer" and also must read things out loud for them to appear real to you, well, again- the Turbotax "free" version may be for you.
I've been using Turbotax online for almost twenty years. Personally, I'd rather pay about a hundred bucks to have someone online to clarify something, e-file and set up direct deposit payment of my refund than take the "free" version and be completely on my own, but I'm kind of weird that way- I don't even get excited by disclaimers, and I can read without moving my lips.
