Situation: My ex wife and I sold a rental property in June 2018.  We divorced on September 2018.  We split the proceeds prior to divorce.  We are each filing separately.  We do not meet any of the exclusions regarding capital gains.  We are responsible for the gain.  I tried indicating 50% ownership thinking the 50% figure may get applied, however, that didn't appear to work.  

Can we simply half the numbers and put identical numbers on each of our respective returns?  The total capital gains from the two returns should still add up.
