I am just finding about this now through an alert on Pro series.  was closed 2 weeks around the email date, so if i received one I probably deleted it going through the several hundred emails I had come in those 2 weeks.  now I see 16 returns could be affected.  13 years using pro series.  The last two years = I am finding a new software company.  This is the last straw for me.  they should be paying for penalties and interest for any money owed on amended returns.  Plus now me a one CPA operation has 16 amended returns to file.
