Expenses with 2 employers + self-employed(artist)

I have the downloaded version of Home and Business and would like to know how/if TT handles this scenario in the software. My wife was employed by two separate employers with T2200 provided. In addition to this, she sold a painting this year and has expenses related to that. After having input all expenses in full in the appropriate an areas, is TT automatically calculating the % of the useable expense for each? And further, are the expenses permitted across all incomes artist and employee, as long as they are portioned?

Thank you for any insight, I just don’t want to make any very obvious mistakes.
