Its kind of a weird situation. I moved out of state from New Jersey to Indiana. And its asking my county/municipal code for my new address so it can inform new Jersey that I have moved. And because new Jersey has 4 digit codes, It will not allow me to input my 2 digit code of which I now reside
Are you referring to your New Jersey or Indiana return?
If you moved out of New Jersey, you do not need to enter a county code.
On your Indiana return, choose Out-of-state OTHER STATE in TurboTax. That will give you Code 00.
