It took quite a while, but at last a favorable outcome. I had received no response since I filed an online protest to the NYS notice saying I had no refund coming and instead needed to pay the small amount of sales tax. About a month ago I started trying telephone calls to NYS but had difficulty connecting until about 2 weeks ago. I was put in touch with a "resolutions unit" and talked to one of those "wizards behind the scenes" who looked at my file and saw that somehow they missed my credit form in processing my return. He said I'd get a notice within about 2 weeks showing no balance due and also the refund requested on my return. The notice came late last week and the refund today. Waiting to see if for 2022 TurboTax will continue not to support that form and NYS not accept PDF attachments and thus forcing paper filing.
