IRS letter to re-submit corporate 2020 return

[Tom in Dunwoody]

The IRS cannot find my 2020 corporate return that was e filed through Turbo Tax. They sent a letter asking that I 're-submit a newly signed copy'.

1) Is it possible/recommended that I e file it again or do I have to mail it in?

2) If I e file again how can I include a scan of their letter?

Sorry ... you cannot efile twice ... you will have to paper file the return.

Thanks. They requested I 'newly sign it', but I am afraid they will then come back saying it was filed after the due date. Shouldn't including their letter stating 'they can't find it' preclude any delinquency?

That and a copy of the email acceptance from TT should work.

Thank you.
