The acquisition of rental property is not added to the expense section of anything, anywhere. You enter rental property in the Rental & Royalty Income (SCH E) section of the program under the Personal Income tab of Premier. You can enter up to 45 separate rental properties.
If you have one rental already, then when you complete working through that first rental you're returned to the rental summary screen. On that screen is a button for "Add Another Rental or Royalty". Click it, and press on.
