I disagree QBI is schedule C income is reduced by 1/2 see tax, contributions to your retirement plans and the deduction for 1/2 your self employment tax. there should be a worksheet showing the calculation. in addition, there are limitations based on taxable income and additional limitations if your business is a specified service trade or busiimess. yo can review form 8995 or 8995a fioor the calculation
from the IRS website
QBI is the net amount of qualified items of income, gain, deduction, and loss from any qualified trade or business, including income from partnerships, S corporations, sole proprietorships, and certain trusts. Generally, this includes, but is not limited to, the deductible part of self-employment tax, self-employed health insurance, and deductions for contributions to qualified retirement plans (e.g., SEP, SIMPLE and qualified plan deductions).
