For a refund deposit date, always go by the actual date provided on the IRS website as we have no control over your return once the IRS has accepted it for processing. The IRS website have the most accurate and up to date information. It gets updated once a day. If you have any inquiries regarding any refund delay, you should contact the IRS or your state Department of revenue directly.
If you signed up for the Up to 5 Days Early Refund Delivery
Up to 5 Days Early Refund Delivery applies when the IRS has processed and approved your refund and a date for direct deposit has been given. For example, if you go on the IRS website and the Direct Deposit is "scheduled" for "February 27th", that's when TurboTax Up to 5 Days Early Option kicks in; it is not based on an assumption of when it might be ready, but rather on the actual date provided by the IRS.
