State tax filing

and it just happened to me: 2 phone calls and a chunk of time with TurboTax "experts"no filing even necessary with a 0 refund and yet the online gremlins charge $40 for an unnecessary filing. even doing a google search results in 'all non-residents must file form D-40b' on several sites. apparently this issue has been going on for 3 years - why hasn't this been resolved?
