Investors & landlords

I have a vacation condo.   I stayed there 84 days.  I rented it 133 days.   This made the income to not be considered passive income due to my length of stays there.  I have a loss. I do not materially participate in running the condo.   A property management company does that.  I thought that I should use Schedule E for Vacation Home Rentals.  However, TurboTax agents stated that I should put it on a Schedule C as a business.  Is this correct?  This would mean that losses can be claimed in the current year against other nonpassive income and future profit may be subject to self-employment tax.  Is Schedule C the correct way to report this?
