Since you indicated (including in another thread) that you lived in New York the entire year, in your own apartment, and are still living there, then you should file as a New York resident for 2024. You would file a nonresident California return IF you have California-sourced income. List your New York address on your return. You would prepare the nonresident return, if needed, first. Then, you may be able to claim a credit on your New York return for tax paid (liability on the tax return, not withholding) to California.
Please also see this TurboTax tips article for more information on filing returns with multiple states.
Since you currently still live in New York, and did for all of 2024, use your New York address. Update your address with the IRS and states when you move back to California.
If you are using a California address, the California tax agency may be more likely to audit you and propose that you have remained a California resident the whole time since you didn't change your address.
You can refer to this booklet from the California Franchise Tax Board about how to determine residency for tax purposes.
