It probably said you got Accepted on the 13th. Accepted only means the IRS verified a couple basic things to know it's really you. They accept it for processing. Then approved comes later.
How long does it take to get approved
Only the IRS and your State control when and if a Federal or State tax refund is Approved and Issued.
If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds
If accepted by the state use this TurboTax support FAQ to check the state tax refund status - https://ttlc.intuit.com/questions/1899433-how-do-i-track-my-state-refund
After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
