CAPITAL GAINS TAX QUESTION

[Timothy Yen]

We sold our Co-Op in 2016 for a profit of just shy of $100,000 in NY (Long Island)  Are we responsible to pay capital gains tax on this?  Didn't the Tax Relief Program in 1997 exempt homeowners from paying taxes up to $500,000 profit for filing married.

I am going to speak to a tax professional, but I thought I'd check here!  I'd like my tax return from 2016 :)
