You can report your rental income (of a farm) on the T776.
In the navigation bar at the top, click on Income > Rental.
531190 is the number for farm rental & agricultural property rental.
FYI: You can look up industry codes t this Stats Can website: https://www.statcan.gc.ca/eng/subjects/standard/naics/2017/v3/index
The problem with that form is when you enter the address which is section-town[product key removed]ian with no postal code because there isn't one, Turbo Tax won't let you file the return.

To resolve this issue, I would advise that you proceed using the note on T776 concerning foreign rentals.
I hope this is useful.
