Thanks for the response. I fall under example 2 with an AGI higher than my QBI (profit from Schedule C) due to W2 wages for my spouse. However, the TurboTax calculation reduces both AGI and my QBI by the deductible portion of the SE tax. Based on your example I would think only AGI should be reduced by that amount and I should get a 20% deduction for the entire business profit on Schedule C.
