Great question - so the amounts are reported but only the NET goes to your income. It will be represented on your tax return as follows:
Form 8949 will report what you paid for the item (your basis) and what you sold the item for (what you received
(there is more here like date purchased and date sold but that doesn't play into this example)
On the Form 8949 the amounts are "netted" to show if you have a gain or loss. In your case you have a net loss of $150
But, because this loss is not allowed the 8949 and the Schedule D will reflect a $0 in the gain/loss fir this along with a code "L" which indicates to the IRS that this sale was personal property and the loss is not allowed.
