First, you are not a sole proprietor. You have a single-member LLC that you have elected to be treated as an S-corp, making you an employee of the S-corp. Schedule C (Form 1040) is not involved.
Both the W-2 and the Schedule K-1 must be entered in their entirety. What is reported regarding section 199A has nothing to do with reporting your taxable wages on Form 1040 line 1a. Your taxable wages are entered via the W-2.
