Only the IRS and your State control when and if a Federal or State tax refund is Approved and Issued.

Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund. 

Use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

Call the IRS: 1-800-829-1040 hours 7 AM - 7 PM local time Monday-Friday

The IRS will hold up your refund until you provide or do whatever the notice requests
