After you file

I'm using windows.  Done with the CD...   I do have a copy of the previewed  copy before I e filed.  But the return is not on the computer with turbo tax any longer or at least on when I bring up the program.   I just don't know what to do now.  I've never had this problem before.  I know it needs to be mailed in but when it was rejected I tried to pay it direct debit, so I need to know can I just mail a check, what forms need to be mailed what paperwork needs to be included (w-2. 1099R, SS docs)?
