Here is another update; I hope that it will help someone else.
After I un-installed the CA forms and found that I was able to file my federal return, I waited until the federal return was accepted by the IRS. Then I re-added the CA state forms to TurboTax. I re-filled them out. Interestingly, the CA LLC form 568 was not automatically included this time, and I was able to e-file the CA state return. Now I can fill out Form 568 separately and mail it in as usual.
