If you are using a whole turkey or chicken carcass, break it into small enough pieces to fit into your Instant Pot.
Add all ingredients to your Instant Pot. Important: make sure the water level stays between the recommended minimum and maximum level on your pot. If you have a smaller pot than I have, you can use less water (or fewer bones and less water).
Attach the lid and close the steam release valve. Press the "soup" button and set the pot to pressure cook on high for one hour.
After cooking, let the steam release naturally for 10-15 minutes before opening the steam release valve. Open the pot after the pressure has finished releasing. Let the broth cool.
Put a large colander over a large bowl. Line the colander with a double layer of cheesecloth. Strain the broth through the cloth so that it collects in the bowl.
Pour the broth into ½-cup cocktail ice cube trays. Freeze.
After freezing, remove the cubes from the trays and store in freezer bags. Now you have bone broth in ready-to-use portions, just waiting to be added to your favorite recipes.
