This is what I have done and seems to follow the feedback given here:

1. I opened the Canadian Registered Retirement Plans Worksheet
2. Entered the Plan Providers Information
3. Selected the checkbox for Registered Retirement Income Fund (RRIF)
4. Entered the total amount received in Retirement income on Lines 7a and 7b
5. Filled out Form 1116 with the same income total and also reported the tax withheld in Canada as Tax Paid

** All values were converted to USD
