My question involves unemployment benefits for the state of: California

I am a freelance writer for a site that pays some people for writing. But, I haven't been eligible for payment, so I, technically, haven't earned any money from them, yet. However, I continue to write for them for exposure in hopes to get a paying job.

Last week, there was a contest going on in which certain "eligible" articles were entered into a sweepstakes (I didn't have to do anything except write an eligible article, which I do on a regular basis, anyway). My name was drawn and I won a prize that is worth, what I believe, is just under $600 in merchandise.

I do have a W-9 on file with them (in case they pay me) and they may issue a 1099, but I'm not sure. I am working with them to find out if this will be included as income, but haven't gotten an answer back, yet.

Would this be included as income? How should I report this to EDD? Will this disqualify me or delay my benefits? If I don't have to report it as income, how will receiving a 1099 affect my unemployment?
