That line on the Schedule E is for Partnerships or Corporations which would come from entering K1 information. If you paid interest on a rental and want to deduct it as an expense, this is how to do it:
- Rental
- Rental & Royalty Summary...edit your rental
- Expenses
- After Mortgage interest is the page "Any Other interest Paid?"
- This will be on Schedule E Part I line 13
