Float right menu items are showing as well as hamburger menu on responsive/mobile settings

Question

I have a fixed menu with a centered logo, left and right menu items. My float right menu items are showing beside the hamburger menu on responsive/mobile settings. Not sure how to fix this.

Do I need to hide those nav items specifically on the @media screen? my code from dreamweaver refuses to copy and paste here

<div class="topnav" id="myTopnav">
    <div class="topnav-centered">   
        <a href="index.html">JACQUELYN MCGARRY</a>
    </div>
    <a href="about.html">ABOUT</a>
    <a href="contact.html">CONTACT</a>
    <div class="topnav-right">
        <a href="shop.html">SHOP</a>
        <a href="work.html">WORK</a>
    </div>
        <a href="javascript:void(0);" class="icon"     onclick="myFunction()"><i class="fa fa-bars"></i>
        </a>
</div>
