I get this in the Review part of the process of doing my taxes on TurboTax Deluxe for Mac:
Form 1099-B Worksheet (Live Nation Worldwide, Inc.): Amount from Form 1099-K has an about from linked Form(s) 1099-K, but the sales proceeds on this worksheet don't match the payment amount from Form 1099-K. Add sale(s) on this worksheet with sale proceeds to match the amount reported on Form 1099-K.
I don't know how to even access From 1099-B Worksheet to make any adjustments for one thing, but for the other, I have checked my entry of the Live Nation 1099-K, and I have put in exactly what is on form (box 1a).
If anyone has any insights, I would much appreciate your help.
If you received a 1099-K for investment (or personal) sales, go the 'Stocks, Mutual Funds, Bonds, Other' in the Investment section.
Indicate that you didn't receive a 1099-B and enter the info from your 1099-K.
If you're using TurboTax Desktop, go to FORMS in the upper right to access forms/worksheets and delete the 1099-K Worksheet so you won't double-report the income or have linking errors.
Your sales will be reported on Form 8949 and Schedule D. Personal sales losses are not deductible, but a gain on sales of personal items (rare) will be taxable as a Capital Gain.
Here's detailed info on Form 1099-K.
