1099s question

I received a 1099s on a sale of my aunt's house, My name and my aunt's name was on the deed when we sold her house. She moved to a senior living apartment. We sold the house for 150,000. Since we are both on the deed, I received a 1099s for 75,000 (half of 150,000). My aunt did not receive a 1099s. How do I enter this in Turbotax. Will I have to pay Capital gains tax, since I actually didn't live at my aunt's house.
