Custom dashboard with extra user information

Hi everyone, I would appreciate some guidance here since I am new to wordpress structure. Um, I have a wordpress website with a theme called Traveler. Traveler allow me to have a user dashboard with some basic fields such as username password and fullname. I need some extra fields though. I saw that via wordpress administration panel i can edit a user and find those fields. For some reason Traveler must have inserted those fields there. However i need to be able to edit them via the dashboard and not via wordpress admin panel. My question is where exactly is the code with the <input> tags that extend the basic fields and allow the user to have extra fields like billing address in the wordpress panel? I think that if I find that i will create some hooks in my dashboard and everthing will work. I searched all over the theme files with the input name which I took though F12 inspector but found nothing. Any ideas? I appreciate any help… in any case this is a wrong place to post this please inform me.
