Hi dondant,
Verify that the pension income was entered correctly and not as trade or business income or other income subject to self employment tax. Take a look at a copy of the return and see if a Schedule C was generated. CollenD3 also made some suggestions on places or records you should look at. It appears that is an input error. Also, look at any loss carry forwards that could generate a QBI statment, but with zero deduction for obvious reasons.
Hope it helps.....
