Here is a trick to use in ProConnect to find an input for a specific item. Works on most but not all parts of the program.
Check Return > Forms > Find the one you want to do input for > locate the box or line you want > Notice the blue shading> That blue shading is MAGIC! Click on it and Voila! you are at the desired data entry point.
Balance Sheet, M-1, M-2 > Sch M-2 (Capital Account) is where this one leads you. In this case IF all beginning capital is proportionate to the percentage of ownership, enter the total for all.
