A word of warning. I withdrew $10k USD from my IRA in 2020. The investment house withheld US tax at 30%. It used to be 15% under NAFTA. The investment house told me that this arrangement was no longer applicable with the demise of NAFTA. So I entered the 30% paid as I filled in my TurboTax for 2020. Now the CRA audited my foreign income and tax and said that I could claim as foreign tax credit only 15% of my IRA withdrawal, not the full 30% which was withheld. This was not picked up by the TurboTax logic. So now the CRA wants almost $2k CAD from me. I did a quick search and found

which seems to corroborate the CRA position.
