State tax filing

It is happening in 3 different states that you are trying to file? Did you file your fed already?  If not, another suggestion maybe... Go through your federal return again.  Maybe something there is affecting the states.  Sometimes things that are allowed to pass in fed won't fly in states.  After you run through fed, run through one of your states and then try to send that state (instead of trying all of the states just to find out that won't work).
