Do I file as a non-resident or resident (no choice of part-year) on a W4? I moved from California to Virginia on August 28th 2024.

I flew to Virginia on August 18th 2024 with the intent of only visiting but made the decision on the last day of my trip (August 28th 2024) to stay and live with my boyfriend. I've been applying to job since then and got an offer. I'm currently doing the onboarding process and have to fill out a W4. If I put my boyfriends address it shows up at "Virginia Resident" if I put my California address it shows as "California Resident, Virginia Nonresident" it doesn't give me an option to put both, there's only a space that says address 2 and when i put my boyfriends address in address 2 it combines my California address and his Virginia address but still shows up as "Virginia Resident" or "California Resident, Virginia Nonresident" depending on which address I put in the first  address slot.
