I am having an issue with Turbotax as well, related to this.
This is on spouse 50/50% allocation for a joint account.
The issue I am having is as follows: the Box 52 and Box 53, which sum to Box 21 on the T3 slip are not being split 50/50 to each spouse when they feed into the T1 Schedule 3. (Boxes 17599 and Boxes 17600).
The software is not splitting the FEED from Box 52 and 53 by the 50% to each spouse, as it does with Box 21 x 50% for each joint spouse, thus causing issues that they do not sum up. I was not able to Netfile because of this issue.
I did a test on a single return and this is a non issue because of the 100% inclusion.
Please fix this glitch. I suggest that since this is a NON issue now the program should simply pull from Box 21 as it was before.
