That offer says "up to" 5 days early, so it's not necessarily the full 5 days. You shouldn't be charged (hopefully) if it doesn't arrive early at all, as compared to the IRS refund settlement date. If you do get charged anyway, we can tell you how to phone TurboTax Support.
"Up to 5 Days Early Guarantee: If your federal refund is not deposited into your selected bank account at least 1 day before the IRS refund settlement date (the date it would have arrived if sent from the IRS directly), then you will not pay the Up to 5 Days Early fee."
