I bought TurboTax last year to replace H&R Block's program, and it worked fine. Last night, I did my Federal taxes on it fine. But then it wouldn't open the state tax form. Took me in a loop back to the "start button" every time. I went on their website query section and saw similar problems were the top question. The answer was to contact them. I held the line for 30 minutes, but having to get up early for work today, gave up.
Be aware if Turbo Tax is your choice. ~Bob
