I am having this problem again this year.  As well as it won't split the interest 50/50 either.  When I overide the 100% with 50 it turns red.  It is only putting the 50% in my account not my spouses.  It really doesn't like it when I overide the 100% to 50, but that's it how I have always done it in the past.  I really don't want to have to enter each slip individually.  That's what the cra download is for.  Is there any fix coming SOON?

@CLtaxes If you are using Forms Mode, then the T3 page has 2 boxes near the top - Your Percentage and Your Spouse's Percentage. You would enter your spouse's percentage in the second box, and then your percentage will be updated. 

In EasyStep Mode, there is a box on the bottom of the T3 to enter your spouse's percentage.

That is the correct way of doing the split, no override is needed.
