Get your taxes done using TurboTax

Thanks That Helped ,  On a joint return, The error comes from when only filing one city return, Taxpayer or Spouse make sure you only populate the one who is doing the city return, leave one of them blank, do not make a selection or populate both Taxpayer and spouse unless you both worked in same city , my case (Detroit).

I selected Non resident, 260 days / 30 days sick Vaca, not worked.  Then the total days I worked in Detroit.

Thanks again.
