I still have TurboTax 2019 (Deluxe), so I did a little experiment. Sure enough, answering "No" to the question "Did you get a 1099-B" brings up a screen where you are asked to "Choose the type of investment you sold". If you choose "Second Home", you are asked for things like the property address, how you acquired the home, etc.
If you've been reading the thread, you already know that this is not how TurboTax 2020 (Premier) behaves....
