Set an Instant Pot to saute and drizzle in the olive oil. When the oil is hot and shimmering, add the chicken, onion, 1 teaspoon salt, and 1/2 teaspoon pepper.
Cook, breaking apart and browning the meat until the chicken is no longer pink and the onion begins to soften, about 7 minutes.
Add in the chipotle peppers in adobo sauce.
Mix all of the spices together in a small bowl and add them to the pot. Let cook until fragrant, about a minute or so.
Add the sweet potatoes, bell pepper, crushed tomatoes, beans, and 1 1/2 cups of chicken broth. Stir well.
Cover, seal, and set to cook on high pressure for 10 minutes.
Quick release to vent the remaining pressure immediately. If the chili seems too watery, you can simmer it on top of the stove in a separate pot to let the liquid evaporate. Taste and adjust seasonings. Serve hot with sour cream, avocados, and cilantro.
