I was issued a W2-G at time of sweepstakes winning. Company also issued me a 1099-misc. Which one do i claim?

I won a sweepstakes and received a W2-g with my winnings. I have all of this entered on my 2016 Tax return Form. I recieved a 1099-Misc from the same company last month. Do i need to enter the 1099? Wouldn't it be double dipping? 

The W2-G has federal and state taxes on it. The 1099 shows the same total tax amount but doesn't have the tax breakdown.
