2015 taxes

[Jill-And-Dallas0]

I am wondering how hosts in the US report Airbnb income. Do you report it using a 1099-K (electronic payment) and again on a schedule "E" or "C?" If so, is that not reporting the income twice? Or is there an place on the schedule "E" or "C" to list the Airbnb tax ID number? 

thanks, Dallas
