Personally, I know of two companies that offer consumer-level tax software for partnerships (1065), corporations, and estates/trusts.
With respect to forms availability, I have been unable to determine whether or not all of their state forms are ready for print or e-file. In fact, I have been unable to determine **anything** related to their products since it doesn't appear as if they have a support forum like this one (TurboTax) or actually any support board whatsoever.
