Go into each file, look at the Client Status.  Make sure it's not just showing the extension was e-filed.  If also the return then you've submitted the return by mistake and will have to submit an amended return.

I'm guessing you are looking at the "next step" column in the EF accepted homebase.  If it says "e-file complete", that's a good thing as long as you are also looking at the return type and see that it is referring to your extension that you filed.
