Could someone tell me how I can know if I did my tax return properly? I did it 2 weeks ago and I haven't got any mail or anything yet.

Did you get a NETFILE confirmation code when you filed your return?

mmm no I didn't! where should I have received this confirmation code?

If the CRA received your return successfully, you should have seen a Netfile confirmation in TurboTax. If you did not receive one, we advise you to file your return by returning to the "Filing Hub" and following the instructions. 

In TurboTax Desktop, how do I submit my return to the CRA using NETFILE?
