How do I download my returns with all the supporting tax forms and worksheets after my returns are e-filed?

I did not originally check the boxes to print these additional worksheets or forms because I just wanted to print what was actually submitted electronically. After I printed them I was going to then download the returns with all the boxes checked so I'd have a record of everything showing how all the figures entered were determined. But when I go back into TurboTax to do this, I don't find this option. All I have is the download with just the returns only. Please advise h.
