You should always report any income that you receive. If you win a game show , you will receive a 1099-MISC form if the winnings are $600 or more. If the winnings are less than $600, you will not receive a 1099-MISC form, but you will still need to report the income on your tax return. You will report the income on Schedule C (Profit or Loss from Business) or Schedule E (Supplemental Income and Loss).
