To get rid of Schedule 6 completely,  you must put a "NO" in "allow discussion" in the "Miscellaneous" screen, (3),    If you say "yes" to allow IRS discussion with preparer (which we all do), then it assumes you are also the 3rd party designee and prints schedule 6 - but WITHOUT AN ADDRESS.   I guess that indicates there is NO foreign address to the IRS.   Go figure.  Unless it's some IRS requirement to print Scdl 6 if there's any foreign income or foreign tax credits  ( even though  taxpayer has NO foreign address), Intuit should  fix this.  Unfortunately, I found no other way to get rid of the darn schedule 6.   I think it probably gets triggered by anyone who has foreign income or foreign tax credits from dividends.
Hope that helps, it drove me nuts trying to figure it out.   Shari
