It sounds like you did it right, and here is what I got when I just tried it:

Before inserting an entry: <p class="p_text_body">A bunch of stuff

After Inserting an entry: <p class="p_text_body" id="toc_3">A bunch of stuff

Did you give each entry a name before you hit OK?

EDIT: So I tried a few on your book and got this in the .ncx file:

<navLabel>
        <text>[BREATH] 001 - Enter, Part 1</text>
      </navLabel>
      <content src="chapter-1.html"/>
      <navPoint id="num_5" playOrder="5">
        <navLabel>
          <text>~1</text>
        </navLabel>
        <content src="chapter-1.html#toc_1"/>
      </navPoint>
      <navPoint id="num_6" playOrder="6">
        <navLabel>
          <text>~2</text>
        </navLabel>
        <content src="chapter-1.html#toc_2"/>
      </navPoint>
      <navPoint id="num_7" playOrder="7">
        <navLabel>
          <text>~3</text>
        </navLabel>
        <content src="chapter-1.html#toc_3"/>
      </navPoint>
    </navPoint>

The #toc_1, etc., were added automatically. I named the entries ~1, ~2, ~3. Here's how it looks in the Calibre viewer ToC panel:
