“Actually” I DO! Paid a BUNCH to BOTH IA AND NE last year.
Income earned in IA was taxed by IA and your income earned in NE was taxed by NE........I don't see a problem.
If you were taxed by your home state of Iowa for the income earned and taxed in Nebraska and didn't get a credit for it then you either have a moron for a tax preparer or you did it yourself.
