Place the rice in the Instant Pot and add the broth or water. (Season with salt to taste if you're using water.) Close the lid and cook on manual high pressure for 24 minutes. Let the rice sit for 5 minutes after the cook time is over, then release the pressure and open the pot.
Add the taco seasoning, chipotle, lime juice, maple syrup, and refried beans to the rice. Stir to combine well. Then add the pinto beans, red pepper, corn, and scallions to the pot.
Close the top and let the mixture sit for a couple minutes to warm everything up.
Season with salt if desired. Serve in bowls and top with avocado and cilantro.
