Turn Instant Pot on to the Saute' feature.
Add olive oil and onions and saute until translucent, about 5 minutes.
Add garlic, stir until fragrant, about 30 seconds.
Add ground turkey and brown until cooked through. If the turkey isn't very lean and you have a lot of grease, you may strain it and return it back to the pot. This is optional.
Add chicken broth (I like to use bone broth for extra nutrients), beans, tomatoes, squash, chiles, cumin, chile powder, salt & pepper. Stir to combine.
Cover and turn the Instant Pot on to the Slow Cooker function. Cook on high for 4 hours, or low for 6-8 hours.
Serve topped with cilantro and plain yogurt or sour cream.
