I recived $97,000 in retropay for past 3 yrs in 1 lump sum on 12/30/2016 which was taxed. Is there a way to put this income separate from my W2 earned wages?

My usual tax bracket was 22% and this retro pay was treated like a bonus and was taxed at 25%, but now my total income for the year puts me in a higher tax bracket and I owe taxes.
