I think the issue has been partly solved. I just efiled both my Fed and CA state returns even though I have a SMLLC. I think I still need to submit the 586 form separately (not clear on that) but turbotax online did let me submit both.
someone on another thread here said they were told by intuit that the problem has been resolved. It would be nice to get clarity on if that meant 586 forms were submitted with it or just being able to file the rest of the state form.
