Do I need to file tax return for a company showing active after final return?

Hello. I had an S Corp with my wife since 2016 in NY. When the pandemic started the business lost its client and there wasn't any activity. We filed a final tax return for 2020 but the Entity is still showing as active. We received a Response to Request for Consent to Dissolution of a Corporation from NT Taxation and Finance stating that we have not filed franchise tax return, and that we must also file returns for MTA surcharge (form CT-3M/4M - tax period ended 12/31/16) with a total of $0.

 

I am not sure what is is that they are requesting since we did not have any MTA surcharges.

 

Do we need to file business tax returns with IRS and/or with NY State if we already filed the final return in 2020 but the company is still showing active?
