Sale of 2d house in Mississippi

My parents deeded their house to the 3 children in 2012.  After my last parent passed away in April, 2018, we sold the house for $120,000 (property valued at $160,000).  The house is located in Mississippi and none of the children live in the state (2 live in Louisiana and I live in Ohio).  How do we show the proceeds from the sale of the house on federal/state taxes.  This was not the primary residence of any of the children.
