every state has a different advocate I've posted a link. there's a map you click on to get the phone number for your state or further down there's a list of states you can click on and even further down, in alphabetical order by state, are the phone numbers. be aware that they are getting swamped because for several months the IRS was not processing paper returns and I'll bet even e-filed ones weren't being processed as quickly as they were in the past. some claimed they filed in late January and haven't seen their refunds. it may also be that the TA office in your state is not yet open. good luck
