I "filed" in TurboTax, but have not mailed my return to the IRS. I noticed errors. How do I get to a screen to change the info in my return after "filing"?

I selected the "file" process in TurboTax, and selected mailing to the IRS.  Upon printing the return, I noticed some errors.  How do I get back to the screens to allow me to change the data in my return?  I do not need to amend the return, since I haven't submitted it to the IRS.
