I don't know what your software is doing but in my version it's clearly a Turbotax issue. Line 68140 is a calculated field and it shows at zero, regardless of entries to the contrary on the T3 box and line 17600 on Schedule 3. It's incredible that this issue has been flagged for over a week now by numerous users and still no resolution. Even worse that this issue is being described by customer support as a CRA issue when I can see with my own eyes that line 68140 is not being calculalated correctly. I've used Turbotax since 2010 but I'll be looking at different tax software next year.
