How to enter NR4 from Canada for my teachers pension plan payments?

I am not receiving monthly pension payments from my Teacher's Union in Canada. I have read conflicting advice on where one should enter the Canadian NR4 income into TurboTax 2024. Do I enter it in 1099-R and enter the same amount into Box 1 Gross distribution and Box 2a Taxable amount? Should the check box be "Taxable amount not determined" or "Total Distribution"? Then do I also enter the amount and taxes paid into form 1116 so I can get the foreign tax credit I paid? It seems like filling in both forms causes TurboTax to count this income twice.

Thanks in advance for any help on this.
