If you e-filed your "signature" was electronic when you entered your AGI or PIN. There is no physical signature when you e-file. If you filed by mail you needed to sign in ink on the line that says "Sign here." Did you e-file or did you file by mail? if you mailed it without signing the form the IRS will mail it back to you; then you have to sign the form and re-mail it.
