State to report my earnings

[jackkgan]

Request your advice on the entry for for the following Turbo Tax question:

Turbo Tax question: Did you earn all of your income in California?

• How much of the <total income> form federal form(s) W-2 did you earn in California?

Question:

1. Should I enter the 1st employer's income from box 16 for the above question  ?
2. Is the state where my income is taxed determined by the value in Box 15? In other words, does CA in my W2 Box 15 mean that the income is considered as earned in California though I lived in New York at that time and my employer's address is Washington DC in Box c of W2?

(Thinking through more: Wondering if box 15 has been entered as CA because my mailing address with the 1st employer may have continued as CA from beginning of 2023 when I was living in CA and working remotely until Nov 1, 2023 . I did not change my mailing address with my 1st employer after that. )

Thanks a lot again!
