You are getting the full amount according to the rules.
According to the IRS (see Q6 at this link), the QBI deduction is the lesser of:
- 20 percent of the taxpayer's QBI, plus 20 percent of the taxpayer's qualified REIT dividends and qualified PTP income' or
- 20 percent of the taxpayer's taxable income minus net capital gain.
Note also that for a "specified service trade or business" there is also a limitation if your taxable income exceeds a threshold amount. For 2019, the threshold amount is $160,700 if single, $321,400 if married filing jointly.
