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.
