SOLVED myself, e-file accepted. TT gave me the wrong efile rejection error message, but did point me to the problem form and lines.
Sched CA had two negative numbers for other income transferred from the federal return. There should NOT be a negative other income. I had a 1099-MISC with $608 in Box 3. In the federal Step-By-Step, TT asked if that was wages. Whether I answered Yes or No, TT did NOT change the underlying worksheet/form. I had to uncheck the box manually and clear the amount in wages on the worksheet for the federal return, which fixed CA also. Total income and taxes for both returns did not change.
The CA e-file rejection was caused by a TT BUG in the handling of 1099-MISC income on the federal return, which transferred to the CA return. Thanks, TurboTax. 😕
