Federal employment laws and most state laws don't require employers to pay out sick or vacation time that has accrued. Check your state labor laws to see what the procedure is regarding payout when leaving a job, but more than likely it will go by the company policies.
See what they normally payout when an employee leaves. If you have an email or a witness that said you did not have to keep time sheets anymore that would be great. Other than that, is there a supervisor or co-worker who can vouche for your 40 hour work weeks?
Good luck
