I was given a 1099-misc form for horse race winnings instead of a w2-g I want to make sure that I dont file it twice or wrong and when can I make the loss deduction ?

I was given a 1099-misc for horse race winnings instead of a w2-g I want to make sure that I file winnings correctly so that I don't file it as 1099 income. So then I can deduct the equivalent losings.
