Occasionally, Schedule 6 is printing with form 1040.  There isn't a foreign address on the return, and the preparer is marked as the Third Party Designee in the info worksheet, but the box checked on Schedule 6 indicates there is no Third Party Designee.

Schedule 6 is not listed in the forms in use area either.

Easy to remove from printed pages, but the schedule will still be sent with the return when it is efiled.
