Dropdown menu stuck behind div

My dropdown menu is stuck behind my main div or trapped within the header. I have messed with the z-index and that has not helped. How would I be able to tell if it was the header trapping it rather than the main div hiding it.

Here is a pic of the issue:

Stuck dropdown

body {
  margin: 0;
  font-family: arial;
}

button {
  border-style: solid;
  border-color: black;
  border-radius: 5px;
}

a {
  text-decoration: none;
  color: blue;
}

#header {
  overflow: hidden;
  background-color: #FFF;
  position: fixed;
  top: 0;
  width: 100%;
  height: 50px;
  border-bottom: solid;
  border-bottom-color: black;
}

.headerSection {
  float: left;
  width: 33%;
  height: 100%;
  display: table;
  text-align: center;
}

.headerSection>.headerItem {
  display: table-cell;
  vertical-align: middle;
}

#asdf {
  position: absolute;
  top: 0;
  left: 0;
  width: 50px;
  height: 50px;
  border-radius: 0;
  background: #1466C0;
  color: #FFAD01;
  border-bottom: 0;
}

#asdf:hover {
  background-color: #00B2EE;
}

.TOC {
  margin-top: 25px;
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 999;
}

.dropdown:hover .TOC {
  display: block;
}

.TOC a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

#main {
  margin-top: 55px;
  z-index: 1;
}
<div id="header">
  <div class="headerSection">
    <div class="dropdown">
      <button class="headerItem" id="asdf">&#9776</button>
      <div class='TOC'>
        <a href='#OS'>OS Information</a>
        <a href='#GI'>General Information</a>
        <a href='#DI'>Domain Information</a>
        <a href='#SUC'>Start-Up Command</a>
        <a href='#shares'>Shares</a>
        <a href='#EV'>Environment Vars</a>
        <a href='#proc'>Processes</a>
      </div>
    </div>
  </div>
  <div class="headerSection">
    <h1 class="headerItem">Windows Audit Script Report</h1>
  </div>
  <div class="headerSection">
    <p class="headerItem" id="aede">Run Time: 2018-06-28 10:11:24.145067</p>
  </div>
</div>
<div id="main">
  <div style='clear:both'></div>

Does anyone have any ideas on how to fix this issue?

It happens because your header has overflow:hidden you should remove overflow hidden please check the changes :

body
        {
            margin: 0;
            font-family: arial;
        }
        button
        { 
            border-style: solid;
            border-color: black;
            border-radius: 5px;
        }

        a
        {
            text-decoration: none; 
            color: blue;
        }
        #header
        {
           
            background-color: #FFF;
            position: fixed;

The issue is the overflow: hidden that you have set on the #header. If you remove that the dropdown should work fine.
