Place the turkey carcass in the bowl of your Instant Pot. (If it’s frozen, be sure to defrost it first.) It may need to be broken into several pieces in order to fit in the bowl.
Clean the vegetables, cut them into large pieces, and place them on top of the turkey carcass.
Add bay leaves, salt, and apple cider vinegar.
Pour in 8-10 cups of water; be sure not to go beyond the “Max” line on the Instant Pot bowl.
Seal the Instant Pot and set it to cook on “high pressure” for 2 hours.
Allow the bone broth to natural release before removing the lid.
Strain out the vegetables, bones, and bay leaves. Transfer the broth to a bowl and allow to cool.
The broth can now be used, refrigerated, or frozen.
