They I way I know how to do this would be to download Electrum-LTC (https://electrum-ltc.org/) and create a wallet. It is very easy to create a wallet with.
Go to Wallet->Private Keys->Sweep
Enter you paper wallet private key and it will take the coins from the paper wallet and load them into your new Electrum Wallet. From there you can send them to whatever exchange you use.
You can tip me in
