Ok thanks for that info. Intuit support said to attached the form to the return, so good thing I double checked here as well. 

I do not have manual entry forms on proconnect; and the NY Form CT-657 is not available under NY Credits in proconnect.  I did enter the credit amount on the NY Schedule K.  That field indicates that it is an override which is weird because I cant find any other place to enter this credit. Why would that field be an override?

But just to be clear I can not attach the completed CT-657 as a PDF to the return and efile it? I have to mail a paper return to them with the form included?
