Knowledgeable would be the word that comes to mind. I had a few questions, started driving for Uber, had other tax years looked at and they found more money i should have received, and got it for me. I used to do my own, and some years paid for others to do it, but this was for sure the way to go. Answered all of my questions so that i could understand them. I have no need to ever do my own again. Easy process too, can do much or all of it online.
