@Hal_Al does the rule of "you can not deduct any losses made on renting a room in your personal residence" also apply if that room is NEVER used for personal use. It is attached to my primary residence, but I never use it. Either way, how does Turbotax (Home & Business desktop) capture the distinction of a room rental in a primary residence and make sure that possible losses are NOT lowering other passive gains on the same Schedule E, for example but rather carries these losses forward just for that column that is about the room rental in the residence.
When I look at the Schedule E that has 'standard' rentals in separate building in column A nd B and the one room I rent out in my primary residence in Column C, it seems to use a loss on the room (Column C) and reduce the overall gain generated by Column A+B in the "total rental income". And that, even though I think I correctly entered in the step-by-sep that this is a "room in my private residence".
