I find it fairly easy to use. It walks me through each step and will occasionally pop up with a "person" asking if I need help or have a question. It's helpful, when it's needed. Just quick answer type questions. I wish the "free" version was really free, but what can ya do. It's convenient and works for me. I have used it for years and haven't had an issue or been audited. I feel if I were to be, that I would have all of the information that I need and would be in good hands.
It's an huge convenience. But the fact is, they tell you up front it'll cost you 45 bucks, then at the end they spring on you that it's actually double that. I don't like the dishonesty. Still, it's a lot more convenient than taking it to a professional and having to wait longer.
