If this particular real estate purchase is your primary residence, you won't enter the purchase of it anywhere on your tax return. You'll deal with it under the Deductions and Credits tab in the "Your Home" section when you get to that point in the program. The only thing you can deduct is any mortgage interest paid in 2019, and any property taxes paid in 2019. That's it for any personal use real estate - be it your primary residence, 2nd home or a vacation home.
