CAVPDI not count CA state tax deduction

I have 2 employers in 2020 in CA. One employer W2 has $779 CASDI which count into state tax deduction. Another employer has $1158 CAVPDI which does NOT count into state tax deduction. Looks like CASDI give tax deduction, but not CAVPDI.

I want to understand:

1. Did I withhold too much CA SDI + CAVPDI?

2. Why CAVPDI do not count as state tax deduction?

 

Thanks for your help
