It may be because I've used Block software for many years, but I find it very intuitive, and I feel it gets better every year. By that I'm referring to what they refer to as "the interview" process in which it asks questions about your tax situation and leads you logically though the process of getting most all the blanks filled in. Even the state package gets better. Most answers to questions can be found included in the app. I have found it necessary to seek other help on just a few unusual, probably rare, circumstances.
Somewhat confusing input. Not in a logical sequence. If you are retired, then your income is entered AT THE LAST, not the beginning, even though you checked the RETIRED box. Too many hoops to jump through. Does seem to give excellent return benefits. Slow to show refund on screen as you work.
