Thank you, @Opus 17. A literal reading of the California FTB 2019 News makes me agree with you. No restriction on the location of the property or automobile is stated, so most likely the Virginia home/car taxes can be deducted on my California state tax form. TurboTax did indeed fill out my 2021 California tax form in just this way, but lacking a positive confirmation in the form instructions, I do appreciate your confirmation on a reasonable interpretation of them.
California does not conform to the Federal $10K SALT deduction limit, so taking this route allows me to itemize my CA return and reduce my state taxes by a considerable amount.
For the Virginia car, I paid both a registration fee (which I believe is not deductible) and a personal property tax (which I believe is deductible). The Virginia definition of these two items may not align with how TurboTax defines them.
