did you receive a 1099-Div?  if so does it show an amount on line 5.  these are 199A dividends.   They are not QBI but Congress in its wisdom decided that these dividends would be a separate component of the 20% QBI deduction.   

there are multiple sources of 199A/QBI income

schedule B - REIT dividends

schedule C net income

schedule E rental income

schedule E income from a pass-thru entity

schedule F

if you have none of these it's likely somewhere along the line you entered something incorrectly. 

form 8995/8995A will show at least what type of income generated the 199A/QBI deduction

if there is still a problem you can't resolve you'll need to contact support.  they can view your return we can not
