my mail in instructions did not print with my tax return documents. can you please send me the instructions?

This was my experience, too. In previous years, the PDF pack always included a cover sheet. This year, the PDF did NOT include the cover sheet, which is where the mailing instructions should be found.  I understand I can go to the IRS.gov site to get the address, so I don't care about getting the instructions sent to me.  However, Intuit needs to be aware of this discrepancy.

Here is a FAQ where you can sign up for updates: Why are there no filing instructions in my printed return?
