Unfortunately, since the NV employer didn't put ID in the W-2 Box 15, TT/Idaho is leaving the Form 43 line 7 Wages line blank and TT/Idaho doesn't visit that field for you to enter the portion of wages earned while Idaho residents.
To fix that you'll have to enter ID in the W-2 Box 15 and the Idaho portion of the total wages (Jan-Jul) in Box 16 to get the return to come out right.
That might violate some e-filing rule and if it does then print out the Idaho return and file by mail.
