Modifying CT1040 form to add direct deposit option

I printed my CT 1040 forms to mail them   As I was reviewing it. I saw that on line 25 it was showing and N in both the acct type and checking no routing number nor account number. I Do not recall see this option when filling the forms out.  I looked to see if i could modify my forms . Didnt happen. What pr where can i do that?
