Hey guys!
I had this same problem - contacted Intuit via Twitter and worked out the solution!
Go to “Forms” mode, then go into the “Netfile Worksheet” (it’s on the list). Go to line 9914 on the second page and “check” it (double click and an X will appear in box). This line confirms that you did not get an advance.
That’s it! After that you’ll be clear to netfile, error resolved.
