Okay, here's an update. I was experiencing the same problem with not being able to file my federal return with the same error quoted above. I thought that my CA return issue was a separate thing, but now it seems like it's connected. I just created a copy of my tax return with all the CA forms subtracted, and I was able to file my federal return just fine.
The CA issue has to do with Form 568 for the annual LLC fee. It has always been the case (until now) that I could e-file my CA return but had to print and mail Form 568 separately. This year, for the first time I'm being told by Turbotax that due to the presence of Form 568, I can't e-file the CA state return at all. It seems strange that this should change with no notice. Why can't we just print and mail Form 568 separately as in earlier years?
