I claimed that a garage sale was a business activity.
You can't deduct housing for a garage sale as you claimed.
The fact that the IRS requires your regular commute and other expenses to be included in your negotiated pay as a W2 employee means that your expenses are effectively considered "reimbursed".
They specifically say you can't deduct even if the employer doesn't reimburse.
"Employees can’t deduct this cost even if their employer doesn’t reimburse the employee for using their own car."

So the IRS does not consider your salary as including reimbursement for transportation.
"you can work as a 1099 contractor rather than a W2 employee."
Companies do not offer that choice to everyone.
