You could add name meaning in the Name Notes/Reason statement - but the About page Name meaning is not editable.
Name meaning suggestions on this website appear to be taken from one source - a Dictionary of American Surnames. Unless FamilySearch decides to broaden this, your surname meaning will not be presented on this website. But I wouldn't worry - if you know the meaning already, and the meaning is widely available (I found it within a minute of reading your request - at https://forebears.io/surnames/kovarovic) it does not really have to be here, too.
In fact, many FamilySearch users get very upset at the meanings provided on FamilySearch for their surnames, as they are often totally "incorrect". A name with the same spelling can differ in meaning, depending on the part of the world it relates to. Take LEE in Chinese compared to its English meaning. How does a computer program "know" which version it is supposed to be looking for?
