Today, 4/5, status is "in process":

The U.S. Department of State has received your application for your passport book on 03/29/2023. We're now reviewing your application and supporting documents. You requested expedited service when you applied. Expedited service can take 7-9 weeks. Our processing times begin the day we receive your application at a passport agency or center, not the day you mail your application or apply at a local acceptance facility.

Does the fact that it's "in process" mean it's been received at a "passport agency or center"?
