State tax filing

No.  You can only file a tax return to claim a refund within 3 years of when the return was due or filed.  So, if you filed your 2020 return in April of 2021, and did not file an extension, then you would be past the time to file a return to claim a refund.   The 3 years start counting back when you would file the claim (which would be today if that is what you are trying to do)
