Recovering Litecoin and transfering to new wallet

Hello all Im a bit green, so I bought some Litecoin several years ago 2014 on my old laptop with coinhub? It was all very primative as I remember. My laptop since died and I have some text written in a book which refers to the litecoin how do I get litecoin onto a wallet? I have what looks like a self generated address 20 characters long.
