Tax Filing for late S Corp election in NJ

Hi

 

My S Corp is formed and elected in WA last year. But I was doing business in NJ last year and the public record shows I have registered S Corp in NJ in 2019 but have not formed completely. I was able to complete the formation yesterday online, but it shows the effective date is 3/12/2020. Can I still file tax for my S Corp in NJ for 2019? if not, is there anyway to back-date the effective date?
