Combine the brown sugar, soy sauce, white wine vinegar, ginger, garlic, seasoning and turkey stock in the bottom of your Instant Pot and mix well.
Give the rice a quick wash so that it isn’t really high in starch and add the same amount of rice in water so that it is good for cooking.
Add the turkey and cook on the sauté function for 3 minutes or until the turkey starts to cook.
Turn off the Instant Pot (pressing the cancel button) and give it a quick stir. Add the steaming shelf over it and using a steaming container place the rice over it with the water in it.
Place the lid on the Instant Pot, set to sealing and cook for 12 minutes on the rice setting.
When it beeps manually remove the lid to force pressure release.
Take the rice out first and give it a quick stir to get rid of any excess liquid or sticking.
Then take out the steaming shelf and stir the teriyaki turkey.
Serve the turkey over the rice.
