Turbo Tax doesn't know if the IRS has sent your refund. After the IRS gets your return they do not update Turbo Tax. Where does it say it was sent?
If you said you do not receive the 3rd Stimulus payment then it was added to your refund (or reduced a tax due). It will be on 1040 line 30 for the Recovery Rebate Credit. How much is on line 30? But if the IRS records show they sent it to you they will automatically reduce your refund or send you a bill. Line 30 is only if you didn't get the stimulus payment or qualify for more. If they IRS changed your return they will mail you a letter.
Double check your bank statements and check your IRS account (both accounts if married) to see what they sent you.

The 3rd Stimulus payment started going out in March 2021 and is for 1,400 for each person listed on your tax return, no age limit. The IRS used your 2020 (or 2019) return to send the checks out fast. If your 2021 return changes and you qualify for more you can claim the extra as the Recovery Rebate Credit on 1040 line 30. But line 30 is only if you didn't get the full amount or qualify for more. Not the amount you already got. The IRS also sent out letter 6475 to tell you how much they sent you . If you are married then each spouse should get a letter for half.
