In the Instant Pot, add in the elbow macaroni, chicken stock, paprika, onion powder, garlic powder, and salt.
Place the lid on, set to sealing, and pressure cook for 5 minutes. Quick release when done.
Add a splash of milk (I start with ¼ cup) and start mixing in the cheese to the cooked macaroni. Stir in ½ cup of cheese at a time, making sure the cheese has melted before adding in more. Add in more milk if necessary.
