The IRS requires you to have gambling winnings in order to deduct the gambling losses against. 

You can only deduct losses to the extent of your winnings and then only if you itemize.

To deduct gambling losses:

1.  Go to Less Common Income.

2.  Go to Gambling Winnings.

3.  Enter your gambling winnings, then a few screens later you see a place to input your losses.
