here are the tax rules unless you are a professional gambler.
gross gambling winnings are reported as miscellaneous income on schedule 1 line 8b. they are not subject to self-employment taxes. you report this income on the return for the year in which you won along with your other income. you pay taxes on the winnings based on your tax bracket which varies depending on the nature and amount of taxable income for the year. I'm surprised you got a 1099-MISC rather than a W-2G. that form does not allow reporting on the proper line on the schedule (it will default to 8z (checking other income on the 1099-misc Turbotax form. If you itemize your deductions, you are allowed to deduct gambling losses up to the amount of reported gambling winnings. If you itemize and take those losses, there will be a problem if the winnings are reported on 8z rather than 8b. Turbotax can't handle this automatically because of the 1099-MISC
