C-corp final tax return and form 966

I dissolved a C-corp on February 2022.  The business used CY.  I still haven't filed my 2021 form 1020. I will have to file the 2021 form 1020 AND wait until next year to file a final tax return, is that right? In addition, am I supposed to file the form 966 now OR should I wait until next year so I can submit it with the final tax return at the same time?  Thank you for helping!
