[What should I print when ineligible for netfile.]

Thank you.  I downloaded the PDF and the Federal Print files.  In both fies the pages where signatures are required there is a bookmark that says DUPLICATE - DO NOT SEND BY MAIL. I am not sure if I should sign off on these pages and send it. 

[What should I print when ineligible for netfile.]

Received a message saying 'The federal income tax return is ineligible for NETFILE.'  .   I have been using NETFILE for years and this is the first time I got this message.

I also checked the CRA Restrictions (https://www.canada.ca/en/revenue-agency/services/e-services/e-services-individuals/netfile-overview/eligibility.html) but do not find anything that is applicable and also my situation has not changed for years.

Do I need to send the full 70-page PDF file?

Also, what other documents should be included when mailing the tax forms to CRA?

 

Thank you.
