CA state taxes not dividing the Capital Account at start between partners

I'm doing the return for a partnership (trust) for my daughter and her cousin. 
I followed the step-by-step instructions, but I can't figure out how to configure the correct figures for the Capital Account at the beginning of the year.
The forms/steps ask me for the starting amount for the partnership, and I've filled in that it's split 50/50, but Turbo Tax just takes the whole amount and puts it in each girls' starting figure instead of half.
