Yes, that is correct.
All of those questions are just TurboTax's attempt to figure out how to fill out the forms correctly. None of those questions are on the tax return. The tax return does not need to know what your main home is or anything like that. The tax return just needs to know the amounts for personal mortgage interest and taxes, and the amounts for rental mortgage interest and taxes. By only entering it in the rental section, in this situation the program will automatically allocate the amounts, and put the proper amounts in the proper sections.
