Once you start your amended return, you will proceed to the state interview section and answer the questions as prompted. You will eventually reach the credits section where the program will ask some questions to ensure you are eligible for the credit. If you are not eligible, the program will let you know. If you are eligible, the program will let you know and proceed to generate your state forms with the credit included.
