There are different ways to do this.

first way

First, see my previous answers, here:

In a nutshell, if you want more comprehensive information on these terms, you should go by the Common Data Elements (CDE) ID of each. You should have the CDE ID, which likely appears in the third row of the data that you downloaded.

With the CDE ID, do the following:

  1. Go to CDE Browser
  2. Go to Public ID Search tab
  3. Put the numerical CDE ID into the Public ID search box
  4. Click on Search

second way

Just go to the GDC Data Dictionary (in particular, the Viewer), and you can find descriptions there, too).
