I believe you meant IRS Form 709, United States Gift (and Generation-Skipping Transfer) Tax Return.
For tax year 2023 if you gave a gift to an individual in an amount greater than $17,000 you have to report the gift given to the IRS using form 709.
Form 709 is separate from your tax return and is mailed to the IRS using the address shown in the Instructions for the form.
TurboTax does not support Form 709.
