I don't have information on what states my exempt-interest dividends are from. My advisor told me the amount toward my home state is quite negligible. What do I do?

My advisor's full response: "The tax-exempt interest from the select Municipal bond funds utilized invest across many states.  So the amount toward your home state is quite negligible to nothing.  Thus making that interest subject to state income tax and only exempt from the federal side."

TT asks for the amount of exempt-interest dividends for each state. I don't have any of that information. What do I do?
