So the fact that there is no option to file a claim yet does insinuate USPS just has it somewhere? I think I will go down there today and inquire.
In all likelihood USPS still has it. It could be at your local post office. It could be in a postal truck on its way to your house. It could be in a USPS distribution hub. You'll need to give it several days before you consider filing lost package claims.
The post office I used for several years in San Diego lost some of my packages from HK for months because they they misclassified them as domestic so they couldn't find them when I'd tell them where they came from. This happened 3 times before I insisted that they check all of their various queues.
