Hi:
I have a question on Qualified Business Income Deduction Info worksheet, Section D2 for partnership. Qualified Business Income is higher than Self Employed earnings from QBI by about $150. This $150 is income from outside ventures by partnership (not related to self-employment). This change reduced the deduction for 1/2 of Self Employment Tax (that is ok), but TT also adjusted my Self Employment retirement deduction, contributed as pretax in Keogh and 401k plan (line 5f).
Question: (1) why was pretax contribution adjusted that had nothing to do with partnership's other venture? and (2) what method was used to calculate that reduction in SE retirement contributions?
Thanks.
