Heat your 6 or 8-quart Instant Pot on the High Sauté setting for 2-3 minutes until hot.
Once the pot is hot enough that water sizzles when flicked on it, add 2 tablespoons of the avocado oil, onion, celery, and bell pepper. Sauté for 4-6 minutes, stirring regularly, until the onions turn translucent. Scoop the veggies from the pot and transfer them to a medium bowl. Set aside.
Add the second tablespoon of oil to the pot. Add the turkey and cook for 4-6 minutes, stirring frequently to crumble it, until mostly cooked through.
Return the sautèed veggies to the Instant Pot. Add the garlic cloves, jalapeño (if using), chili powder, cumin, oregano, paprika, and cayenne pepper (if using). Cook for 2-3 minutes, stirring frequently, until fragrant.
Turn off the Sauté feature. Pour in the chicken broth, scraping up any brown bits from the bottom of the pot. This is important not only for flavor but also to prevent burning.
Next, pour in the salt, soy sauce, corn, beans, chopped tomatoes, and tomato paste, being careful to just pour them in, creating layers. Do not mix or stir!
Lock on the Instant Pot lid and pressure cook on high for 15 minutes. Natural-release the pressure for 5 minutes, then quick-release the remaining pressure.
Unlock the lid, give the chili a good mix, and season it to taste with additional salt. Enjoy hot with your favorite toppings!
