Brown your ground beef in the Instant Pot on "Saute Mode". While the beef is cooking, continue stirring it so it doesn't stick together. Add in bell pepper and onion and saute until they turn golden brown.
Rinse beans and drain corn. Add the remaining ingredients into the instant Pot (beans, chicken broth, corn, diced tomatoes, garlic, chili pepper, paprika and taco seasoning) and season it with a bit of salt.
Set the timer to 25 minutes and let the Instant Pot come to pressure and cook. Once it beeps, do a "Quick Release". For serving, top it with some grated extra sharp cheddar cheese, chopped green onions, and a dollop of sour cream.
