Litecoin core wallet private key

Hello community
I had a litecoin core wallet on my laptop I’m trying to recover my litecoins I have the private key how can I recover the litecoins I’m downloading the core wallet again what step should I do to recover thanks for the help laptop is Mac

once you are done sycing the blockchain with the newest version…open console under the debug menu and then type:
importprivatekey (private key)

make sure to encrypt your wallet with a password and make a backup…DO NOT FORGET YOUR PASSWORD…YOU CANNOT RESET OR RECOVER YOUR PASSWORD EASILY…

if you have already set a password for the wallet prior to importing the new key…
you will need to unlock the wallet first before you can import a new key…

Dont forget to make a backup after you import the key and save it on a flash drive or something and do not loose it
or you can send your coins to an exchange once your wallet is finished importing the key as well
