During booking or check in you can add your Known Traveller Number (i.e. Global Entry, Nexus, etc.) to the booking and in most cases this will give you Pre Check. That's independent on what passport you are using to travel.
Even easier: make an account with the airline directly and add the Known Traveller Number to your profile and add you booking to your account as well.
Sometimes I present two passports at Check In, especially if I leave the departure country on a different passport than I'm using to enter the destination country. That's typically not necessary in the US. Technically you are required to exit the US with your US passport but there are no exit controls, so it's a moot point.

It's worth noting that TSA Pre✔️ is available if the airline participates in the TSA Pre✔️ program.
TSA lists participating airlines on this page.

It doesn't matter which passport you use for travelling (but remember that you must arrive in the US with your US passport), TSA Pre is not related to that.
You need to add your Known Traveller Number (written on the back of the Global Entry card) into your booking (at least 24h before you check-in create your boarding pass). This is easiest on the airline's website - just look up your trip by its code, and add the number.
