I received a 1099 from my property management company for a rental house. But, Turbotax also uses a schedule E. Isn't that taxing the same income twice?

The 1099 reports the full rent paid without deducting expenses...so around $16K. With all our expenses considered, we actually lose $600 for the year. So, schedule E is $-600. But, Turbotax puts both $16K and -$600 as income on separate lines.
