Ambrosia sold some furniture at a garage sale and was paid through an online app. In January, she received a Form $1099-$K$,$ Payment Card and Third Party Network Transactions, reporting the payment. How should this be reported on her tax return?

The sale of personal$-$use property is reported on:

Form $1040,$ line $1,$ with no adjustments allowed for any realized loss.

Schedule D $($Form $1040).$ If there is gain, it will be taxable, but any realized loss is not allowed and must be subtracted as an adjustment.

Schedule $1,$ line $8$j$,$ with expenses reported as a miscellaneous itemized deduction on Schedule A $($Form $1040).$

Schedule C $($Form $1040).$ Any profit will be subject to self$-$employment tax.
