Sportage probably has a turbo if it says turbo intercooler, I doubt that they'd just put a sticker there to fool buyers.
As far as your question goes, a turbo is an exhaust driven supercharger. And intercooler is a mechanism which cools the compressed air generated from the turbocharger. Ofcourse it's all much more complicated than that but that should give you a better idea of what the term means.
