but the $250,000 is against the gain, not against the sales price.(but maybe that is your point)
what was the purchase price of the home originally?
and wait--- you stated 'ex-spouse'. what was your legal marital status on 12/31/19. if you were legally divorced on that date, your filing status is 'single'. you can't file 'married - separate'. that is just the way it is. (I assume you do not have any children in your custody which would otherwise turn the filing status into Head of Household)
just report everything in half .
