Turn instant pot to saute. Once hot, add olive oil, carrots, celery, onion and garlic. Saute until slightly softened, 3 to 4 minutes. Turn off saute.
Add remaining ingredients to the instant pot. Set to high manual pressure for 7 minutes, make sure it's sealed. Allow for natural pressure release for 10 minutes (if you don't do this stock will shoot out of the pressure valve and make a huge mess not that I know from experience).
