Ok I found a walk-thru that helped me add them and those Security Errors seem to have cleared.
But I want to make sure I put them in the right area in my .htaccess file.
Does this look right:
# BEGIN rlrssslReallySimpleSSL rsssl_version[5.1.3]
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP:CF-Visitor} '"scheme":"http"'
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
</IfModule>
# END rlrssslReallySimpleSSL
# Really Simple SSL

# End Really Simple SSL
# Really Simple SSL
