You are correct.
ST rentals that average 7 days or less are reported on Schedule E and not subject to self-employment tax unless you provide substantial services; ie: cleaning of the rental everyday, changing the sheets everyday, and providing other "hotel" like services.
I recommend you go back through the rental question section to make sure you answered all the questions appropriately. The other issue to be aware of are the questions related to your participation; passive, active and material participation.
