After you file

When I fill out my taxes with turbotax, I followed the instructions very carefully, but I did not see the step 3.  When I checked on the status of my refund, there is no record that I filed. I kept the e-filing on PDF.  Please advise what can I do now. This is the third year I have used Turbotax and never before I had a problem.  Did not see step 3. Why cannot I communicate with a person on Turbotax?
