ProSeries appears to be miscalculating MAGI for purposes of the Roth IRA contribution limitations.  It is adding back SE health insurance, which is not supposed to be a modification for MAGI purposes.  Has anyone else experienced this?  I ran the calculation on the IRS worksheet (manually) and it seems ProSeries is definitely miscalculating.  SE health insurance is not an add-back.  Line one had to be overridden to match the IRS worksheet and allow the Roth contributions.  See line 1 of the worksheet.  It seems to be OK for traditional.  Why?
