If you had a flexible spending account or other day care benefit at work, it is recorded in box 10 of your W-2 and you must include form 2441; it will be re-created every time you try to delete it. If you spent money from the account and are not reporting qualified expenses, the money will be added back to your taxable income. If you forfeited the money (never got reimbursed and lost the money) you must report that as well, but the money will not be taxable.
