TurboTax is telling me to attach only the W-2 to form 40 and nothing else, but when I look at the state of Oregon publication at this link:
https://www.oregon.gov/dor/forms/FormsPubs/form-or-40-inst_101-040-1_2020.pdf
on page 4 it states the following:
Federal return. You must include a copy of your federal Form 1040 or 1040-SR and Schedules 1 through 3 (if applicable), 1040-X, or 1040-NR with your Oregon return. Without this information, we may disallow or adjust items claimed on your Oregon return.
