I sold my house in 2018.  But to sell it, I was required to replace the septic tank, install a Randon fan system, and install an arsenic absorber to the water system.  Where exactly can I enter this?

If the home was your primary residence, and you have lived in the residence for two of the past five years, you can exclude capital gain up to $500,000 for joint filers or $250,000 for single filers.  If this is the case you don't have to
