State tax filing

i did my taxes. the state taxes of NY say i owe 0 and im owed 0. they did the look over and says theres no issue . when i try to file it says that i have to file by mail bc theres an issue that stops it from e filing. however NY state doesnt allow you to file by mail if its prepared electronically.  so it needs to b e filed. i went over it numerous times and cant find this issue. needless im at a loss and i need to fix it because i have no choice but to e file.
