I prepared my 2019 taxes online last year. I guess I never submitted them. I already completed the forms on turbotax though. Can I just print them out and mail in now?

I thought I’d submitted it, but obviously never did. I also have two states to file with. I am just wondering if printing the completed forms and sending them to the respective agencies (Federal, NY and CA) with a copy of my W-2 is acceptable, or is there more that is needed? Also, is the saved file all that I need, or would it be a different form completely?
