pending after more than 48h and no email

[ds26gte]

Hi, I filed on April 16, and TurboTax still shows my returns as "pending" after 48 hours, and after the tax deadline (18th).  A previous answer to a related question by someone else suggests I would get an email within 48 hours saying what the problem is, but I don't see any email either. How do I take it up from here?

Did you get a NETFILE confirmation number from the CRA? If you didn't, then your return wasn't filed.
