Don't know if this will apply but here are some notes I made in past years....
One thing I found was my QBI credit was not as much as I thought it would be. Because I had a business loss the prior year and it carried it over and took it into account.
This post must be about 2018 returns if my Jan 2019 was right.

The developers revised the questions that are asked in regard to the Qualified Business Income Deduction. To reestablish your eligibility for the deduction you'll need to revisit the Business section, edit your business, click the Continue button on the Your [business name] Business page and answer the questions again. Be sure to answer Yes if TurboTax asks if you want to provide additional info that might be needed later.
