After you file

I was moving ahead with my 'plan' as noted above to print out my taxes to pay them now that my amount changed & I stopped payment on my original ACH payment for 4/15/21. However, TT is says: "The following return has been transmitted. Don't file returns by mail that have already been transmitted electronically...".

 

So, how do I now file my correct return and pay my new amount due 5/17/21?
