A gift is not deductible on any tax return. Ever. You have no loss to claim. Not a penny. Simply work through the Assets/Depreciation section and for each individual asset listed select the option for "I stopped using this asset in 2019". Then on the "Special handling required?" screen select YES and finish working it through. That does it. 2019 will be the last tax year you will report this property on your tax return. If it gets imported to your 2020 tax return next year, you can delete it from your 2020 return *NEXT* *YEAR*.
If the value of your gift was more than $15,000 (and I"m sure it was) then you are required by federal law to report the gift to the IRS on IRS Form 709 - Gift Tax Return. *YOU* *WILL* *NOT* *PAY* *TAXES* on the gift. But you are required to report it.
Take note that the form 709 has absolutely nothing to do with any tax return in any way, shape, form or fashion. It's completely separate. The form 709 is not included in any version of TurboTax. You can get the blank form at https://www.irs.gov/pub/irs-pdf/f709.pdf and the instructions at https://www.irs.gov/pub/irs-dft/i709--dft.pdf. Mailing address for the form is included in the instructions. *DO* *NOT* mail the form with your tax return. It "DOES NOT" get mailed to the same location as your tax return.
