Hi Jordan,
Assuming that a 'geopoint' question is included with the survey, you can click on the location button in the map display.
If there is not a geopoint question included with the survey, the map view and location button will not be visible, and Survey123 will attempt to capture the device's location. If the collection device is not connected to a network or wifi, the location will end up at location (0,0) which is explained here...Frequently asked questions—Survey123 for ArcGIS | ArcGIS
