Terminate Multi-Member LLC - can both initial return and final return be checked at the same time?

Scenario:

 

Multi-member LLC formed in Oregon in 2018 with EIN but not open for business.

 

Looking to dissolve LLC, would I need to file form 1065 at all? If so, would I check both the initial return and the final return at the same time? Or, just the final return box?

 

Thank you.
