@Anonymous_, The Schedule L and the shareholder basis calculation (for the purpose of TurboTax Business) are two very different things that you continually seem to be combining erroneously.
I am not trying to argue with you but I do believe you have a misunderstanding about all that I have stated. Your misunderstanding is evident in your statement "the developers are most likely not going to add some sort of "basis calculation" for shareholders nor automate all of the entries that may be required". FYI: The developers have already added the basis calculation in the form of the Stock and Loan Basis Information Worksheet AND the Shareholder's Basis Statement AND the Shareholders' Basis Report for each shareholder in the corporation's 1120S. The PROBLEM is that the shareholder Capital Contributions, is missing from the interview. The Capital Contributions are needed to complete the calculation accurately.
