The IRS issues most refunds within 21 days if filed electronically. 4–6 weeks if filed on paper, assuming that there's no delay and nothing is holding your return.
Even though the IRS has already sent the funds, the bank may take up to 5-business days to process and deposit into your account
You should track your refund directly from the IRS Website. These websites have the most accurate and up to date information.
