Double trigger RSU CA non resident tax question

Hi, I worked in the same company in 2023, 8 months in CA, 4 months in WA.

I have 100 double trigger RSU granted when I was in in CA. It was vested at $0 with time condition in CA. Time condition was removed and RSU was 'settled' into sellable stock at $100 in WA.

1. So do I calculate my CA taxable RSU income as

100 * $100 * (time work in CA between grant and settle / total time between grant and settle)?

2. This number is part of my w2 box 16 state wage value and affect my CA state income tax. Do I need to work with the company for a w2c if I believe the number is off? What other options do I have?
