My roommate and I sold our home last year that we co-owned equally for about $300,000, and we split what we made. How does this affect our taxes?

We lived in this home together over 3 years and we are aware of the $250,000 tax exclusion for real estate sales. I just need clarification for this on our situation as we are not married, but co-owned and split the sale equally. When we signed at closing, there was a tax document that would report the sale of our home to the IRS because we 'made over 250,000 from the sale' and were not married.
