"Lost my AirPods Case, but I have one AirPod in my possession: I currently have the right AirPod in my ear at the moment, but I lost the case which also holds the left AirPod in it. I cannot figure out how to locate it using the Find My app as it just tracts where the right AirPod is. May I get some help?"

About AirPods and Find My:
If Find My was enabled with these, then note that the local shown is based off of the last time the device they were connected to was most-recently connected to the Internet. You are not going to see the location where these are, unless it is with that device. This is because AirPods are not assigned their own IP Address.
