This is normally referred to as the "qualified business income" or QBI deduction. Not sure why they used "pass through deduction" here. Because that terminology is easily confused with a different tax break that some states enable called a "pass through entity tax" which lets a business owner pay state income tax from their business and deduct that amount on their (personal) federal return.
Now I'm imagining a very masculine-presenting cis man inviting everyone to their big gender reveal party, only to anti-climactically reveal that they identify as a man.
