Sorry, I'm a dinosaur, here. I still file paper returns. Do very little online anything for the reasons you state. I just get the fed/state tax forms/books and go through them line/line. Doesn't usually take all that long and I don't find it particularly difficult. Might need to find an accountant this year due to some new business activity.
I used Turbo Tax ages ago and was not happy. At the time you answered a series of questions and then it gave you what it thought the appropriate line items you needed to complete. Well, since it didn't ask the questions regarding LLC's or other small businesses, didn't work out too well for me. I did much better on my own with paper/pencil.
But that's just me. Might work for you if you have a relatively uncomplicated tax situation.
