The easiest way to do it is
through the Forms mode. Create the T2125 - Statement of Business or
Professional Activities for the one spouse, with all the amounts split. Then
select Edit>Forms>Copy/Transfer Form and click “Copy” to make a copy of
the T2125 onto the other spouse’s return. Then you can just edit the 2nd
spouse’s form where necessary. The main thing you will have to edit is the
partnership second, because on Spouse A the partner will be Spouse B (50%), and
vice versa on the other one.
