DianeW777:
Thank you for your suggestion. While on the "Other Taxable Income" page, I encounter the following text: "Do not enter income reported on Form 1099-MISC." If I were to input my 1099-MISC Box 3 sum here, I appear to be not following official TurboTax policy despite doing so completely removing the Schedule C Loop I had been stuck in all weekend while attempting to do the right thing. Is there somewhere else I could enter this information without encountering a similar 'Don't do this' disclaimer? "Other income not already reported on a Form W-2 or Form 1099" looked promising; but once inside, the word "wages" is everywhere. Since net investment proceeds are not "wages," that seems like a dead-end also.
