After you file

When you e-file your tax return, there is no physical signature on the tax form.  You "signed" electronically when you entered your AGI.   If someone who is ignorant of how e-filing tax returns works is requesting a signed copy of your tax return, print a copy of the Form 1040, take out a pen and sign on the line that says "Sign here".   If it was a joint return, both spouses need to sign.
