Part-Year California Resident

Hello, I moved to California in August of 2024. I started earning wages in CA at the same time. I am trying to complete the 540NR and the instructions read, "Do not deduct income that was earned while a nonresident of California or from sources outside of California. There must be a difference in tax law. Generally, if a California resident cannot subtract the income in column B, a nonresident or part-year resident may not subtract income in
column B. " This reads to me that I am no allowed to deduct my earning while I was a nonresident of California even if the income I earned during the non residency was done from CA. I read elsewhere that only wages made from CA sources or when in CA had to be taxed. Can you help me understand why I would need to pay CA state taxes on wages I earned and already paid taxes on in another state? I'm hoping this is incorrect.
