You are confusing "approved" with "accepted". The first step after a tax return is efiled is for the IRS to either accept or reject your tax return. This normally occurs within 24-48 hours. You indicated your return was accepted so that likely occurred within that time frame. TurboTax gets no information and is prohibited from inquiring about the status of your tax return once it is either accepted or rejected.
After it is accepted, the IRS then processes it before the return is approved. Sometimes the IRS needs more information or sometime it makes adjustments to the return before it is approved. That process usually occurs within 21 days from the time it is accepted. After it is approved the IRS issues a direct deposit or refund check if you are getting a refund. There are times when the IRS takes weeks or maybe even months to approve a tax return. There is nothing TurboTax or anyone else can do to change the process time.
With the IRS currently not taking phone calls, the only thing you can do to track the process is to to watch the status on the IRS tracking web site: https://www.irs.gov/refunds
