Retirement tax questions

I see.  This still makes me believe that you have only one employer, yourself as self-employed and, as such, are subject to a single plan limit even though your income from self-employment comes from separate sources.  The CBP then adds to the single plan limit.  This would explain why TurboTax is giving the result that you see.  Your 2.5% ownership interest in the partnership would not seem to change that.
