This is my exact problem as well. Loss on T5008 and line 68140 on T936 not populating. Would appear to be a TT issue, BUT when I entered same information in Wealth Simple, same thing happened-Line 68140 doesn't populate.
So somehow CRA is involved. Maybe CRA and the tax filers software coordinated in some way such that this issue affects all tax filers.
Wherever the issue lies, it sure is frustrating!
