Yes, paper filed Oregon return.

The actual Form 40 says "Important: Include a copy of your federal Form 1040, 1040-SR, 1040-X, 1040-NR, or 1040-NR-EZ. Without this information, we may adjust your return."

Form 40 Instructions Say: "14. Your federal return(s) and schedules"

And for my research, i have found a few that say just to attach page 1 and 2 of the Form 1040 and not the schedules.
