How do I access Schedule 11 and S11 from my 2016 return, which I did online via Turbo Tax (the PDF copy is only 6 pages long and does not include detailed schedules)?

Please make sure that you are looking at the archive copy of your return and not the condensed CRA version.

Here is how you can print a copy of your full tax return in TurboTax Online: https://turbotax.community.intuit.ca/replies/2648070
