Place 1 cup of chicken broth into the Instant Pot.
Place the trivet into the instant pot and then place the seasoned turkey breast onto the trivet, skin side up.
Set the Instant Pot to cook for 40 minutes on high power.
Once the 40 minutes is up, allow the pressure to release naturally.
Remove the turkey from the pot and cover with tin foil until ready to serve. Or, if you would like the turkey skin to brown more and be crispy, turn the oven on low broil. Place the turkey on a baking sheet and broil until the skin is crispy and golden. Watch constantly as it can change very quickly.
Turn on the saute function of the Instant Pot.
Add butter to the liquid that was leftover from the turkey, in the instant pot. Stir until melted.
Gradually add flour while whisking constantly. Cook for 3-5 minutes.
Stir in the heavy cream. (If there are lumps, an immersion blender works well.)
Turn off the heat. Whisk occasionally, until desired thickness. (It should continue to thicken in the residual heat.)
You may pour the gravy over the turkey breast or serve it on the side.
