After you file

I just did some checking and it appears that this problem goes back at least two years.  The problem showed up in both my 2015 and 2016 files.  I am lucky in that the error did not cause a change in my reported SS benefits.  I had some contract work in both those years and that caused the smaller of my calculated taxable SS benefits to be based on my wages.  I am not going to look back any further.
