Surprisingly I get a lot from Kentucky, even though we have an Amazon distribution center near Kenosha.
You should know that the return address on the label is not the address that the package shipped from; it is a returns center for the package. Amazon has two returns centers in Kentucky, Lexington and Hebron. If your package shipped via Amazon Logistics Amazon has actually redesigned their shipping labels last October, with the shipping fulfillment center code on the lower left box. Examples include PHX6, ONT6, or LGB3. Usually the fulfillment center codes are named after a nearby airport.

Also a lot from Kentucky. For some reason, a lot of the Amazon packages I order end up getting here late because they get shipped to Columbia SC instead of Charlotte then here. When I notice it hasn't arrived and I get a "Sorry your package is late!" 95% of the time, it's been delivered to Columbia. Don't know what's going on there.
That facility in Columbia is likely a Sortation Center. The Sortation Centers are regional centers that sort packages to local Amazon Logistics Delivery Stations or to USPS Post Offices for last mile delivery.
