Lost filing 2019

Hello All,

 

I filed my tax extension for the 2019 tax year and I filed by mail both the state and Fed returns.  They are both subsequently lost.  I reached out via secure email to my state and  sent them my return (via email) and they credited my account.  What should I do about the Federal?  I try to call and I can't get through.  You can't email.  Kind of at a loss since it has been awhile since the filing 10/2020.

 

Thanks!
