Had same reason that NY State return could not be E-filed: Return claims a Solar and Wind Energy Credit carryover. Problem: on worksheet value for the credit was "0." (Zero and decimal point). To access that, I went to FORMS on the top menu, and all active forms appeared on side menu. Scrolled down past Federal Forms to New York Forms, and further down to "Tax/Credit Wks" and on that worksheet, item 26 "SOLAR AND WIND ENERGY CREDIT CARRYOVER" showed zero and decimal point, which should have been okay mathematically but didn't work with TurboTax programming logic rules. Tried to delete the zero but that operation wasn't allowed. So I raised it to $1000, then deleted and backspaced until the line was BLANK. Went back to Review and as I went through, it worked okay. Success! E-filing was finally enabled!
