I'm a non-resident so cann't e-file, I printed my return and it's 6 pages. When I save my return it is 22 pages and says DO NOT FILE - COPY. Which should I file?

The 6 pages is your T1 general income tax package condensed which shouldn't say "do not file, copy". This is the one to be sent to the CRA. The other copy with the 22 pages will have the do not file/ copy on it. That will not change as the only one that you can send is the condensed packaged which is what the CRA requires.

Thank you for choosing TurboTax.
