When completing non-resident tax no provision to credit my corporation's correct filing of my 14N form, which should have given me a refund. After Turbotax filed the incorrect file, I obtained a copy of the Nebraska form from Nebraska, which showed in line 28 of 1040N, I marked up a copy and mailed it to Nebraska on time. Today I received a Balance due notice with penalty. I tried contacting Nebraska by phone to straighten out the mess, but Just like TurboTax Nebraska does not provide an option to settle these problems by talking to a live agent.
