Do I need to include all pages of my tax return when I am responding to the CP80 notice ? (It is 589 pages including my worksheets etc. What are the schedules to be included ? do I need to include the 1099 forms ? 


You only send to the IRS the exact same federal tax return as was sent originally.  This would be a signed and dated Form 1040 plus any other forms and schedules included with the tax return.  These would be those which have an Attachment Sequence Number located in the upper right corner of the form and/or schedule.  DO NOT send any worksheets or forms which are indicated as for your information only.
