I spoke to TurboTax and was able to determine what to do but not intuitive.
As a non resident required to complete Schedule A (Statement of World Income) and Schedule B Allowable Non-Refundable Federal Tax Credits.
On Schedule A line 1 (to be populated with line 23600 net income from your T1) this amount cannot be changed or overridden. TurboTax does not populate until other amounts are manually entered. e.g. once I entered an amount on Line 6 (employment income outside of Canada) line 1 was populated. This Schedule A does not populate the data entered on the Personal Information Worksheet.
Once Schedule A is completed amounts on Schedule B are populated from information on Schedule A and T1. Do not check box to prorate credit on the Personal Information Worksheet. Your non refundable credits will be calculated based on dates entered on 1st page of T1.
