from lepinia.it/home to lepinia.it , how to redriect existing links on google?

Hello,

I changed the site url from lepinia.it/home to lepinia.it

the site is working fine, but the links on google that refer to lepinia.it/home are now broken and gives me error 404

I followed the wordpress guide copying the index.php in /home to the root directory

this is my actual htacess on the root , (wordpress is installed on /home folder)
