When will Turbotax Premier support Form 8990? The inability to attach even a PDF for efiling is a nonstarter. Should I use TTBusiness? Switch to a different software?

I want to efile (and must for my State). Didn't find out until this late K-1 arrived that TT Premier doesn't support this. TT Business might be an option, but I'm worried that the program will be too complicated for me, as I don't own a business. I'm really in a bind for this year. For the future, at least give us the option to add a form before efiling? Otherwise, I'll have to try to find some other software.
