One issue could be a carryover QBI loss from the previous year. That would reduce you current year QBI income by losses sustained in previous years.
Another issue could be if you reported dividends or capital losses in your business entries that would limit your QBI income.
Also, you need to subtract from your business income any self-employment tax deduction, self-employed health insurance or self-employed retirement plan contributions to arrive at your QBI income on which the 20% is applied.
