The question "What type of High Deductible Health Plan did you have on December 1st, 2019?" has nothing to do with California requirements.
TurboTax is asking this question to test for a specific situation: where you had and contributed to an HSA in 2019 under the last month rule, but where you did not stay under HDHP coverage for all of the "testing period" which is essentially all of 2020.
Any California requirements would be addressed in the California interview, not in the HSA interview on the federal return.
This is a legitimate question within its narrow scope but which is lacking the context that would show that it does not apply to most taxpayers.
