I chose print & mail but now I want to efile. I can't figure out how. I am in Canada.

You can go to Filing Hub, and from there choose 'Netfile CRA' option. It will let you Netfile if eligible.

1. Select File from the left menu.
2. Review your order if you haven't already.
3. Select Start next to File your return.
4. Follow the on-screen instructions to NETFILE your return.

Thanks for choosing TurboTax.
