Just keep waiting.  You are not alone. Millions are still waiting. Turbo Tax only gives you an estimated date. The IRS usually pays most refunds within 21 days. But these are not normal times. This year is taking the IRS longer to send the refunds. There are millions more people filing returns to get the Stimulus payment.
