Form IT-255 is included in the TurboTax state program for New York. On the "New York credits and taxes" screen, under Your Home, click the Start button for "Installed Solar Energy Equipment in 2023." When you enter the information, TurboTax will fill out Form IT-255 and include it in the New York tax return.
Apparently the form was inadvertently omitted from the list of available forms.
