Total rental and royalty expenses not adding up correctly

We rented our house for over 14 days on airbnb. We reported our income of about $600 in schedule E (Wages and Income -> Rental Property and Royalties). For Expenses, we inserted $180 for maintenance and about $640 for supplies. We elected not to deduct interest payment or any further expenses. After reporting everything, on the "Review your Rental Summary" screen, it only shows our expenses at $40. What happened? I would expect expenses to be at least as high as income.
