Hi, Victoria and welcome!
My name is ***** ***** I will be assisting you today.
When you apply for Global Entry, it includes TSA Pre, so you don't need to apply for and pay for them both.
You can call TSA's Universal Enrollment Center's phone number and ask them to cancel your existing Precheck appointment.

I hope this helped, and wish you much good luck with your GOES application.
