Have you contacted your bank about this? Does the bank have a record of your deposit? If they have no record of your deposit, you must follow up with your state to inquire about your refund. Additionally, you mention the state site shows 3/2, but the state's date will not apply to the federal refund. You can track your federal refund at www.irs.gov/refunds.
