No do not mail the cover sheet or any instructions or worksheets. Just mail the actual 1040 tax return and any schedules and forms. Be sure to get a tracking number from the post office when you mailed it. The IRS doesn't Accept or reject mailed returns. They take them all. If they have any questions or adjust your return they will mail you a letter. Be prepared for a long wait. If you have a refund it may take 10 months or more.
