S Corp effective date issue

My LLC came into existence on 02/29/20.  Soon after a month or so, I filed form 2553 and got effective date of S Corp as 02/29/20.

I'm filing my taxes 1120S .  In the form  section A  asks for  S corp election date.  I enter 02/29/20 , it doesn't allow me to transmit the returns.  In the section G -  is the corp electing to be the S Corp this year,  I checked 'Yes'.  

do I need to again submit  2553 form again along with the returns?  I know that its not required as I already did.

The only option left for me is to print and mail the returns. 

Can anyone help me here so I can transmit my returns through eFile?
