Business & farm

The income rightly is reflected on the IRS form 4797 Sales of Business Property.  To also report the income directly into your Schedule C misrepresents the income.

I recommend reporting the income only on the IRS form 4797 Sales of Business Property.

If you want to acknowledge the receipt of the IRS form 1099-K, consider entering the income as other income.  Then reverse the income by using the box "This amount in box 1a is too high or includes some personal transactions."  The reversed amount is reported at the top of Schedule 1 Form 1040.

In your tax return work papers, make sure you explain where the 1099-K income is correctly reported should a tax authority ask questions about the income at a later time.
