The IRS states that most refunds will be received within 21 days (business days) if you e-filed & choose direct deposits. Mailed in returns can take up to 6 weeks. States differ on when they issue refunds.
Once your returns are accepted, only the IRS and State would know when you will receive your refund. TurboTax does not get any information about your refund.
