Im in the same boat. I used TT for many years and because I have 32 installment sales form 6295. TT tax software would not handle it (restriction on number of forms). So they recommend that I buy proseries as a single user.   Nightmare as I'm not a professional tax accounted and don't need so many pin numbers/irs id's.   

I liked TT .  Any suggestion as I do my own taxes and have a single very large return.?
