Won't let me NETFILE

It won't let me NETFILE. I have already paid Turbotax. When I get to the next screen after I paid, it says I can't NETFILE.
I don't have foreign tax credit, non resident, SR&EB
Every year I was able to do NETFILE. This year wasn't any different in my tax return. I have copy/paste turbotax message below:
 
-------------------------
You do not qualify for NETFILE for the following reasons:

1. You have indicated that one of the NETFILE excluded situations applies to this return. This return is not eligible for NETFILE. Common examples of this are, you are claiming foreign tax credits from more than 3 countries, an emigrant or non-resident, claiming SR&ED expenses, etc.

----------------------------

 

Do I absolutely HAVE TO print and mail it in at this point?? Where did I enter wrong?? Is there something I can fix and go back to NETFILE it??

 

Please help!
