1099-MISC for state-granted stipend

I received a stipend payment for California's Mental Health Loan Assumption Program (through OSHPD) in which I receive a certain amount paid directly to my loan lender in return for 12-month employment at a non-profit mental health organization.  I've received this stipend for the last four years and this is the first time I'm suddenly receiving a 1099-MISC from the state that awarded the stipend to me.  I thought this wasn't taxable?  How do I go about this?  There's no way I suddenly need to pay $2500 in taxes....do I??  One suggestion included documenting it as a business expense, but TurboTax requires me to upgrade to a self-employed edition.  I also don't want to do that if this really is taxable.  Help!
