How to redirect all links to particular url same server domain

I used redirect function in cpanel it doesnt work as i want. This is the code from htaccess RewriteCond %{HTTP_HOST} ^mywebsite\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.mywebsite\.com$ RewriteRule ^/?$ "http\:\/\/mywebsite\.com\/about\-uspage" [R=301,L] mywebsite.com redirects to - mywebsite.com/about-uspage -- Fine... But if anyone opens for example.... mywebsite.com/any-other-link then it doesnt re-directs to mywebsite.com/about-uspage which is what i want. Note that mywebsite is a parked domain on my cpanel and mywebsite is not my primary cpanel domain name.
