The California (CA) 100S form has an input box for CA Corporation Number and CA SOS File Number. I called the SOS and they told me as an LLC with an S-Corp election I will only have the CA SOS File Number, not both. Turbo Tax requires something in the CA Corp Number field. Per the instructions, one of the options is "LLC is Filing as a Corporation". To me I elected to be taxed as a Corporation vs file as a Corporation but wanted to make sure that was the appropriate response since leaving the field blank causes an Error flag on the form.
