Echoing @IMPERIUMLAW ; I'm the filer for a California General Partnership. TurboTax expects the Secretary of State Filing Number to match the rules for LLCs - must start with 19 or 20. I'm not filing for an LLC. My partnership's filing number is 12 digits, not starting with 19 or 20.
The workaround of entering all 0's allows electronic filing but would only create confusion at the FTB that I don't need to rebound to me.
I ended up filing by mail; so 1980s.
