I am working on a return for a couple who are dual-status filers for 2020 (10 months in US, then moved to Canada and became nonresidents of US last 2 months of 2020).  Trying to properly record the Social security income per US-Canada tax treaty.  How do I get Lacerte to pick this up right.  Does the field for "Canada Article XVIII" assist with this?  It creates a negative number in other income on Schedule 1.
