Overall quite easy to use. However, it regressed into a continuous loop when I finished with state returns and it kept wanting me to review only to show the page for a second state. I finally had to just go on to "file" to get out of it.....very confusing. Also, I still find it difficult to navigate to one particular part of my filing such as a specific 1099-INT I needed to adjust; it forces you to start up at the top of all those INT entries. I also found it confusing on how it identified a block I needed to fill but didn't take me to that page; rather, it just shows one place to enter the number. I really needed to go back to the entire form or entry page again to understand better what was needed.
I have been using TurboTax for a very long time and I love it! It has made tax season less stressful. I love it's ability to store previous years tax returns, so the following year is seamless!
I use it every year because it is overall very good. Suggestion follows: First time filing small business income - cost of supplies is the most important deduction and should be listed automatically on the page for deductions instead of having to search for it which took quite a while.
