The best way to make any QBI information corrections is to go back through the interview process instead of editing the forms. This is due to the fact that many of the QBI questions rely on other questions to correctly calculate the deduction. On the Wages & Income section of your return, choose the income type that is reported on your Schedule E (rental property or Schedule K-1) and Edit/Update the section. Verify your entries and answer all the questions through the process and ensure all the QBI questions/fields are correct.
