No, I didn't enter anything for SE tax. Lacerte is automatically calculating it based on my Schedule C and a partnership K-1 that the taxpayer received that showed SE income. The deduction for 1/2 SE tax shown on Schedule 1 matches the QBI reduction for the Sch C QBI and the partnership K-1 QBI. It's so strange that an S-Corp K-1 is showing a QBI increase for 1/2 SE tax...
