Sale of inherited land between siblings

Father passed away 9-22-2012. He had no will. Mother quick claimed her interest to the 4 siblings in 2015. The land mkt value on TN property data website shows $13,300. On 3-28-2016 the land was sold and one half of the proceeds went to our father's brother and the other half was split between myself and my 3 siblings. We each made $6062.50. When I enter the market value and the amount I made from the sale, it shows a loss. Just want to make sure we are entering this correctly.
