Turn on the Instant Pot to sauté and add oil and butter.
Once the butter is melted, put in the onion, celery, carrots, and poultry seasoning. Cook for 3-4 minutes until the onion softens.
Add garlic and sauté for 30-60 seconds until it smells good.
Pour in ¼ cup chicken stock and scrape the pot's bottom with a spoon to get any browned bits. Then, turn off the Instant Pot.
Add more stock, cooked turkey, noodles, salt, pepper, and a bay leaf. Mix it all together.
Put the lid on, make sure the vent is sealed and set the Instant Pot to cook for 1 minute on high pressure.
After it's done cooking, wait 10 minutes for the pressure to release naturally.
After about 10mins, release the remaining pressure by turning the venting knob. Be careful of the steam.
Take out the bay leaf and stir in cream, lemon juice, and peas.
Put the lid back on for a minute or two to warm everything up, then serve..
