Add the chicken, taco seasoning, salsa, and broth to the instant pot.
Cover and set to pressure cook for 30 minutes. Make sure the vent knob is sealed. (It will take 10 -15 minutes to come to pressure before timer starts).
When the cook time ends allow the pressure to naturally release about 10 minutes. Then release the remaining steam from the vent knob.
Remove the chicken from the instant pot and shred it with two forks. Place the chicken back in the pot to let it soak up some of the juices for a few minutes or until you're ready to serve.
