Sweepstakes winnings 1099-misc

I received a 1099-misc for a sweepstakes I won. in the amount of $4776.00 for the estimated value of the trip.  The trip had to be used within four months after winning or it would be forfeited, I had some medical problems and was unable to use the trip. I did not receive anything from the prize company other than a letter stating I won. I did not get tickets or anything from them . What should I do about this 1099 ?
