Business & farm

My father is retired and sold a rental property in Desert Hot Springs, CA. He has a part time job and made about $10,000 for the year. He bought the property for $30,763 in 1998 and sold in for $137,600 last year. i just want to make sure all the information is correct before I submit the taxes.  And I don't know how turbotax came up with the 32K figure when he only shows a net loss of 17K. Any help would be appreciated. Thank you
