Oh and I forgot to say that my best friend is working for H&R Block this year doing people's taxes. She's was going to school to be an accountant but dropped out a few years ago with a few classes left. She never took any specific classes on taxes and she just took a short 4 hour training course with H&R Block.
as mentioned before, the H&R folks are basically filling in a tax software program with information you give them. there are some who are good and know additional questions to ask to help tease out more things, but there are alot who are doing exactly what you'd do with Turbo Tax.
