Get your taxes done using TurboTax

Oh oky makes more sense now. To make it clarity I for got to put my e-signature on the 2020 tax return. So I was reading on one of the comments said to not worry after it got accepted. I know that the irs does not give any info about if it got approved or not. It wasent been 21 days yet. I went to the irs website n it said there wasent no info at this time about my taxes. So do I just print out the form and sign it with ink? If I have to mail it where address do I mail it to?
