do i need to report 20000 cash gift to adult child

Gifts given to family members, friends or other individuals are not deductible.   Gifts received are not taxable to the person who received the gift, and are not entered on a tax return.

If your gift exceeds the yearly limit ($19,000 per individual)  imposed by the gift tax rules, then you will need to complete a Form 709 gift tax form and send it to the IRS, although it is very unlikely that you will owe any tax.

TurboTax does not support Form 709.  It is not an income tax form and would not be included as part of an income tax return.

No, you do not report the gift given on a tax return.  Since the amount given is greater than $19,000 you must report the gift on IRS Form 709.  Form 709 is not included in TurboTax nor is it filed with your tax return.  It is a stand-alone form that is completed by you and then mailed to the IRS.
