In TurboTax Online, please select "My Info", then "Province of Residence" from the left side menu ≡. From the drop down, choose Non-Resident S.216, and then answer the questions down below. Click "Continue" to save your changes. 

Then, from the left side menu ≡, select "Provincial", then "Get Started". Instead of provincial taxes, this section will ask you questions about your Non-Resident situation, and the appropriate forms will be generated.

Unfortunately, this guide doesn't work.
TurboTax is not able to generate T1159 form. The S216 Non-Resident feature in TurboTax isn't working.
