how do i correct federal tax id on w-2g

[DoninGA]

IF the Payer's or Winner's Taxpayer Identification Number (TIN) is incorrect on the Form W-2G then you need to contact the payer to get a corrected W-2G.

don't bother unless TurboTax is throwing up an error message or there are taxes withheld. In the other cases, the issuer's TIN is not sent to the iRS.

if correction is needed

To correct incorrect information on your W-2G form for gambling winnings, follow these steps:
Go to the W-2G section under Wages & Income in TurboTax.
If you need to edit the W-2G, select Edit next to the incorrect information.
