I have a couple of investments in LLCs that owns property in various states. In some cases, there is no state source income and it seems in all those instances there is no need to file. In other cases, there is rental income and/or capital gains. I would think I have to file in those states, but TT is saying that it does not think that i need to file in a particular state based on the information entered for my federal return. How can that assessment be made without knowledge of allocations source income by state? Obviously I don't want to do the work and/or buy the state module and file unnecessarily. Thanks in advance.
