I am having the same issue outlined above.
I have gone back through the Business Information sections multiple times, as well as the forms Mode to review the form information.
In order to recreate the issue. Create a Business that has formed date in 2020, for me this was September 2020.
As well as S Corp election date the same as the formed date above.
This causes the 1120S Section G to be checked Yes correctly, but as the form indicated you should not have to send in the 2553 form if you already did so.
I can't seem to find a worksheet/information sheet in the forms that has the "Yes, it already made the S Corp election" answer. This is where I think the program is having the issue, it thinks that any new S corp election needs to file the 2553 form regardless of answering the question, say it was already elected.
