Investors & landlords

I'm trying to help my 88 year old mother with this same issue. Do I enter the information under 1099S on turbo tax or under a different area. I did not find the line items you mentioned in your reply while looking at where they want me to enter the 1099S. Do I just go to the investment section and not enter it under where turbo tax says a 1099S goes?

Thank you for any/all help with this
