What program do I use with a foreign pension. I am receiving a Unite States Social Security pension.

You can use the "Standard" version of the software to enter in your SS US pension. 

Here is the link to access it for the online version: https://turbotax.intuit.ca/personal-tax-software/online-tax-software.jsp

Or if you prefer the downloaded version here is the link: https://turbotax.intuit.ca/personal-tax-software/download-tax-software.jsp

Because we have a tax treaty with the USA, you are protected from being double taxed. 

Go under your Income tab - T-slips, at the bottom you will find Foreign Income, this is where you would enter your Social Security pension.
