Put olive oil in pot and turn pressure cooker to saute function. Place chicken breasts into pot and allow to cook each side for about 2 min. per side so the outsides are no longer pink. Turn pot off. Move chicken to the side and pour in a bit of your broth so you can deglaze Instant pot. (meaning scrape bits of stuck on chicken off the bottom of your pot)
Sprinkle taco seasoning on top of breasts. Pour chicken broth on top of that, then add salt if desired, followed by the can of corn. Spread kernels out evenly inside pot.
Add drained can of beans on top of that, spread out evenly. Sprinkle in uncooked rice evenly inside pot.
Pour jar of salsa on top of rice so all of it is covered.
Close pressure cooker lid and steam valve to sealed.
Set to pressure cook, high, for 12 minutes. Then do a quick release.
Remove chicken breasts and put on a bowl to shred. Then put back into your pot with other ingredients and stir.
Serve this in bowls topped with: sour cream avocado, cheese, etc!
