This add-on applies when you received Form 1099-K for business activity, self-employment, gig work, sales of personal property, or other payment transactions.
Upload every Form 1099-K received, along with transaction reports and records identifying what the payments represent. The form reports gross payments before adjustments for fees, refunds, credits, shipping, discounts, or the original cost of property sold. The reported amount is not automatically the amount of taxable income.
