Start the Instant Pot on "Saute" mode and let it heat up. Wait until the screen says "Hot" and then add the olive oil and the beef.
Brown the beef for about 5 minutes, adding the onion, garlic, carrots, celery, bell pepper, spices, and salt.
Continue sauteing for a few minutes more, just until the veggies begin to soften.
Add the beans, canned tomatoes, tomato puree, and beef stock and stir everything together well.
Place the lid on the Instant Pot and seal the lid. Place the release valve on "sealing".
Cook for 10 minutes on "Pressure Cook".
When the Pressure Cook time is finished, carefully turn the release valve to "venting" using a long pair of tongs or another long kitchen tool so you don't burn your hand, arm or face. It's a good idea to do this under an exhaust fan in your kitchen, if you have one.
When the pressure has released, open the lid and serve in bowls with a dollop of sour cream, some cheese, and some fresh parsley or chives.
