1120PC

My tax practice is very specialized. I do primarily insurance companies. Not agencies but insurance companies. I need software that supports the 1120PC. I have been using HR Block because it is the only thing I have been able to find. It is not the best software. Basically, it is a step above fillable forms. I have called Drake, CCH & TaxAct. No one supports 1120PC. Does anyone know of software that supports 1120PC?

Lacerte doesn’t either

UltraTax seems to have it (I don't have any 1120PC clients but I can it appears that I can do a return). I would wager a bet that CCH ProSystems/Axcess has it as well.
