This queso is the best for many reasons. One being that it doesn't have processed cheese, artificial flavors/colors in order to make this queso creamy.
In Instant Pot add chicken broth, sour cream, cream cheese, diced tomatoes drained, garlic cloves minced, salt and pepper. Place lid on instant pot and make sure the steam release valve is locked.
Once the float valve drops open lid and stir for 1 minute. The cream cheese will still not be fully melted yet. Pour half of the shredded cheese in the instant pot with the black beans.
