I filed my return in June and still haven't received my refund or any contact from CRA that my return even made it. I'm concerned something went wrong.

Please log back into your TurboTax account to see if it shows that you filed it. You would have had to go to the "file" section of your return and NetFile from there. Once it goes through you will receive a NetFile confirmation number. If you never received one then  you never completed the last step.

I filed my tax return using NETFILE but didn't receive my refund or Notice of Assessment. What do I do?

Thank you for choosing TurboTax.
