After you file

The actual Federal return may only be one sheet of paper. Page 1 appears at the top half; the signature section in the middle; and page 2 at the bottom.  That would then be followed by Schedules 1-6 if applicable, and Schedules A, B, C, etc if applicable.  Or do you also want all the worksheets?
