Why do I need a Schedule E when I DON'T OWN RENTAL PROPERTY

See if there is a Schedule E listed and if so delete it

Click on Tax Tools on the left side of the online program screen

Click on Tools

Click on Delete a form

Rental income would typically result from an entry on Form 1099-MISC, in box 1. It could also come from an entry on a schedule K-1in box 2 or 3. If you don't think you have any, you can delete the schedule E, as mentioned by @DoninGA
