You can't go directly to the question about Qualified Business Income (QBI). You have to step through the whole business income interview again. The question about QBI is at the very end. On the Business Summary screen, click the Edit button for your wife's business. Stepping through the interview is mostly a matter of repeatedly clicking Continue. It only takes a minute or two. When you get to the Business Expenses screen, you don't have to go through the details of the expenses. Just click Continue again. The next screen is the question about QBI. You can change your answer, then proceed through the follow-up questions.
This procedure is for the TurboTax Premier CD/Download software for 2018.
