Non-Arizona municipal interest

I have looked at the other responses to my problem. I am unable to submit both my Fed and State taxes because I have an error: "Form 140: Line 13 Non-Arizona Municipal Interest has been entered. This entry requires a schedule listing the payors and the amount."

 

I am unable to enter anything on the page. There is no drop-down menu, as suggested in some answers. I cannot get to the actual form.
