TT walks you through all the steps in a clear concise manner. You can zoom down in a section for explanations to be sure what you are entering is correct. You can also access several help/support systems. I have used TT for years; it gets more sophisticated every year but remains very easy to use.
What's great about it: step by step is thorough and easy to follow
What's not so great: when going back through a section, TT deletes some answers to they have to be re-entered
The state sales tax forms would not work in February, I had to wait till Mid March to get them to work. Even though I bought the deluxe edition they wanted charge me for the for an upgrade to do my state return. I kept getting an error on box 14 my wife's w-2 because It kept telling me to select other from the drop down list, when the correct selection was blank for electronic filing it took me awhile to figure it out.
What's great about it: I worked just like it did for the last 10 years, No real learning curve
What's not so great: Some of the forms were not ready in Februrary.
