First of all this is a mailbox service, not a passport agency where you can renew your stuff. But to answer your question, yes you do have to make an appointment and fill out the necessary paperwork and turn it into the proper address and or facility in order to renew your daughter's passport.
On this page are the documents you need and procedure: https://travel.state.gov/content/travel/en/passports/apply-renew-passport/under-16.html If you need to make an appointment, it gives you the option to see where you can complete the process
I am very sorry, I do not know about these procedures I live in Mexico and the one who does the paperwork is the father of my children and I am helping him, could you help me and tell me how I am looking for the right place to do this process please ? and if it is in a place that does not need a much better appointment. thank you very much for your attention.
