I guess it also depends on why you are asking.
......if you are referring to the tax-exempt $$ in box 12, then when it asks for what state produced the $$ in box 12...the easiest answer is to indicate it came from "Multiple States" (last state selection in the list).
________
IF you know the $$ amount of box 12, you may be able to break out just the $$ that came from your resident home state (you don't have to do so...but you would have to calculate the exact $$ amount from information the bond fund provides separately.) A couple states (CA, MN), have restrictions on whether you are allowed to do this, and IL doesn't allow it at all for bond funds.
