Thanks for your answer and Clarification. I will file under Turbo Tax Category
"Canadian Registered Pension Income" (option 3 above). This seems like the best place for those receiving a Canadian Pension under treaty.
It would be nice if Turbo Tax definition would expand the definition as it talks about RRIF and RRSP.
However RS publication 597 states
A pension includes any payment under a pension or other retirement arrangement, Armed Forces retirement pay, war veterans pensions and allowances, and payments under a sickness, accident, or disability plan. It includes pensions paid by private employers and the government for services rendered.
Pensions also include payments from individual retirement arrangements (IRAs) in the United States, registered retirement savings plans (RRSPs) and registered retirement income funds (RRIFs) in Canada.
So it would be helpful for Turbo Tax to expand this definition going forward
I note following the process on your link "option 4" Turbo tax flags the missing EIN as an error. So I doubt I can efile
