Deductions & credits

Yes, you can.

The IRS would generally consider prize money from a sport as hobby income, especially if the expenses are greater than your income. 

Hobby income is not taxable for self-employment taxes and it is reported on line 21 of form 1040, and expenses from the hobby are reported as a miscellaneous itemized deduction (this deduction is limited to the gross income from the hobby).

However, if your participation in this sport is conducted as a trade or business, you would could upgrade to TurboTax Self-employed and report the income and expenses on schedule C.

To report hobby income and expenses in TurboTax, follow this path in the program:

  1. Click on Federal on the left-hand menu.
  2. Click on Wages across the top.
  3. Scroll down to Less Common Income and click Show more.
  4. Click Start or Revisit on the line labeled Miscellaneous Income, 1099-A, 1099-C.
  5. Click Start or Revisit on the line labeled Hobby income and expenses.
  6. Enter your hobby income and all of your expenses in a lump-sum figure. If the expenses are more than the income, you can simply enter the income amount on both lines (TurboTax will apply the limitations regardless of what you enter).
