Wildcard Manually on hostname

I have a wilcard certificate and I would like to install it manually in the hostname but I can’t find the place to put the keys.

I do not want to generate a new one that lasts three months from the webpanel, I want to put one of mine that lasts 1 year.

I have tried putting it in:
/usr/local/lsws/admin/conf/webadmin.crt andy webadmin.key and also in

/usr/local/lscp/conf/key.pem
/usr/local/lscp/conf/cert.pem

/etc/letsencrypt/live/domain.tld

But not work.

Sorry my bad english.
