Get your taxes done using TurboTax

There are a couple options you can choose from. 

First, you can print and mail in the return with the required documents.

You can use 00-0000000 for the Payer ID and your own address for the Payer's address (this works since your state would be the only state that may require tax on the winning)

Or you can enter the winnings as if you did not get a W-2G. The income, whether reported form Form W-2G or as "Other Income" is reported on the same line of your federal tax return, which is Schedule 1 line 8b, which flows to Form 1040 line 8.

For this third option, go back to 

Wages & Income

Less Common Income

Prizes, Awards, and Gambling Winnings

delete the W-2G entry 

return to that same section and select "We didn't receive a W-2G"

Enter the amount of winnings form the W-2G

Continue and enter losses if applicable 

Select DONE

If Federal tax was withheld, continue to

Estimates and Other Taxes Paid

Other Income Taxes    START

Withholding not already entered on a W-2 or 1099    START

Select YES and enter the tax withheld
