Oklahoma Amended return TT printed 511-EF..?

Amending Federal and OK return. Federal amended return was electronically filed (even though I had to manually change values on Column A of 1040-X.. but that’s a whole other TT issue).

OK original was e-filed (511-NR). OK amended 511-NR must be mailed, so I printed the return and it included a 511-EF. Instructions appear to indicate this is only used with certain supporting documents when you can not attach PDFs to an e-filed return. Why is TT giving me this form? I am not e-filing this return and I selected return filed via mail on TT. Safe to assume just ignore this form and not send it? Even if I needed to send supporting documentation I would just include such with my amended return and no 511-EF needed, right?
