Taxes owed when participate in class action lawsuit; 1099-MISC is wrong!

I was the lead plaintiff in an Equal Credit Opportunity Act (ECOA) class action lawsuit, we won the lawsuit, the total settlement was $300,000, and I got $10,000 for being the lead, but I received a 1099-MISC for $300,000!  How do I file my taxes and specifically, how do I deduct the $290,000?  The $290,000 went to the attorneys and other parties involved in lawsuit.
