I can’t seem to remove a section on rental income that’s appearing in my income section but not applicable. Any one able to advise how to remove this?

In TurboTax Online here's what you will do: 

1. Select Tax Home from the top of the left side menu and search for “Rental properties”.
2. On the “Rental Summary” page, you can delete any properties that are there.
3. Then you can go back to Step 1 & continue to the Rental Profile page, where you can uncheck anything unneeded.
