We call it the Passthrough Deduction, but it is also called the Sec 199A deduction or QBI Deduction. It is the 20% of Taxable Income deduction (its not a simple 20%, there are several variables that influence the calculation) for business owners of passthrough businesses like S-corp, Partnership, and Schedule C.

It is important to make sure the Business Data has been entered correctly in the top of the screen to accurately calculate the deduction.
