My notes say
(1) the 1/2 SE tax deduction,
(2) Self Employed Health Insurance deduction, and
(3) employer retirement contributions
need to be subtracted from your business profit to determine "Qualified Business Income" (QBI) for the 20% deduction.
But One thing I found was my QBI credit was not as much as I thought it would be. Because I had a business loss the prior year and it carried it over and took it into account.
