Place all ingredients into instant pot bowl insert in the instant pot.
Make sire the lit and vent is set to sealed.
Click pressure cook high for 8 minutes. (Note, the cook time stays the same regardless if you double or triple this recipe, it till just take longer for the instant pot to come to pressure. If you are using frozen chicken adjust the settings to 10-12 minutes. **See further explanation in the text above
Allow the instant pot to release naturally then turn the valve to venting (note, this will get REALLY HOT, do not put your face over the vent and use a pot holder to open)
Open the lid.
If desired, check the temperature of the chicken. It should read 165 degrees F. If it does not you can either shut the lid and let it rest for 5-10 minutes OR place it back in the instant pot on high for 1-3 minutes.
Shred the chicken breast.
