@ye4jimI believe you just report your net RRSP that is deposited to your US account in USD, same as if you were taking an IRA distribution. My step son is an accountant in CAN - I'll ask him next time we talk.
As far as the CP and OA - I just do a year end report on my checking acct to find the amts deposited in USD, add those to her SS and that's it. The person who said to add it as other income on the 1040 is wrong, based on what I have learned from other tax accountants. CP/OA is treated the same as SS so it has to go through the SS taxable amount calculations from the SS worksheet for 1040 line 6 - this takes into account the % of SS that is taxable and gets you from line 6a to 6b. The "other income" category ends up on line 8 and is not reduced in any way by the SS taxable amount rules - note that the CA tax paid may end up on line 10 as an adjustment. I definitely agree that turbotax is lacking in sufficient explanations for these situations.
