I have a 1099-MISC showing gambling winnings for an app, but I can prove I lost more than I won. How do I deduct my losses?

[DoninGA]

Gambling losses can only be deducted up to the amount of the gambling winnings.
Gambling winnings are reported on Form 1040 Schedule 1 on Line 8b. The amount from Part I of Schedule 1 Line 10 flows to Form 1040 Line 8.
Gambling Losses are reported on Form 1040 Schedule A as a Other Itemized Deductions. Gambling losses are not a one-for-one reduction in winnings. Your total itemized deductions reported on Form 1040 Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.

You can only deduct losses up to your winnings IF YOU ITEMIZE as opposed to taking the standard deduction.  Normally, gambling winning are reported on a W2-G.   Winning and losses are reported in the same place in TurboTax.  

Go to Less Common Income, then Prizes, Awards, and Gambling winnings.   Select I didn't receive a w-2G.  Enter the amount from Box 3 of your 1099-misc, and on the next screen you will be able to enter your losses.   You will need to keep clear records of your winnings and losses, especially  since your gambling winnings were reported on the wrong form.
