My father (the other shareholder in my company) uses HR Block to do his taxes and Form 7203 isn't even in their system. It never asked for it and you can't even find any mention of it in their help section! I finally managed to put mine together in TT after about 5 hours pulling old tax files and doing all the calculations for the last 20 years. Once I had the data, I had no trouble entering it in TT. I'm still bitter though, because I spent an hour on the phone with TT trying to get help with it and the person I was on with was COMPLETELY clueless about the form.
