I have NR4, code 43 -Distribution received is added to my income, refund goes down, but taxes paid in Canada are not being consider. Looks like a double taxation.

I have NR4, code 43 - and had a question answered by TurboTaxKarenJ  - I am following all instructions, but as a result, I don't see any Foreign credit being calculated. Distribution amount I received from Canada is being added to my income, refund goes down, but taxes I paid tin Canada -25% - are not being consider. Looks like this is a double taxation. Is this correct? 

Please help
