I'm confused because I take it TurboTax does not assist with filing (but last year I think it did). Is there a way to file via TurboTax now that my return is filled out?

If you are eligible for NETFILE, you can use TurboTax to file your return. Here is how to submit your tax return to CRA using the NETFILE service in TurboTax Online: https://turbotax.community.intuit.ca/replies/3210262

If you are not eligible for NETFILE, you can print out the CRA copy of your return and mail it in to file. To do this, follow the steps on how to NETFILE, but on the “Filing your return(s)” page, click on the “Print & Mail Your Returns” button instead.
