What are you getting a refund from? If you have no income you probably didn't need to file a return. Did you have any tax withholding taken out of any W2 or 1099 form?
Did you efile? Was it Accepted?
Did you go all the way through the File tab, through the 3 steps and hit the big orange Transmit Returns Now button?
If you used the Online version you can check your efile status here

When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile. And check your spam folder for them.
When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc. What does it say?
Then what does the IRS say? If your return was Accepted or mailed then check IRS Where's my refund
