Proconnect by Intuit will prepare form 990 but that is professional software and not the same as "Turbotax".

Turbotax (personal -- Basic, Deluxe, Premier, Self Employed) does not include federal form 990 for charities.
Turbotax Business (corporations, trusts, partnerships) has never before included form 990 and I can't find another source that says it will.
