Where do I put my 1099-S form if I sold a house I built that isn't my primary home?

I bought the land.  I paid the contractors to build it.  Never occupied it.  Sold the house in 2019. 

 

I received a 1099-S.  I'm using the 2019 downloaded version of Turbo Tax. 

 

I tried following the prompts but it keeps telling me to put it in the business investments section.  The section assumes I got Schedule Q but I didn't.

 

Should I just declare it under Schedule C?
