non-resident state filing

[MH2]

I received prize winnings from an online casino (based in Europe). Prize winnings were paid by a 3rd party from which I received the 1099-MISC form. The 1099-MISC has a Newark, NY address on it. 

Even though I live and work in California, would I still need to file a non-resident state tax form for the state of NY even though I technically didn't win money in the state of NY?

Thank you in advance.

MH2,

The location of the payer listed on the 1099 form is not relevant, you earned the money as a CA resident.  Consider the example of Fidelity brokerage accounts: the payer National Financial Services LLC lists a New Jersey address on their tax forms but there is no NJ taxation involved.
