The 3rd Stimulus for 1,400 was an advance for your 2021 return and will be reconciled on your 2021 return we are filing now. So if your 2021 income qualifies it will be added to your return. Check 1040 line 30 for the Recovery Rebate Credit. It doesn't matter what your 2019 or 2020 income was. The first 2 stimulus checks were based on 2020 returns.
I don't understand what you think Turbo Tax could notify you about. The date you file doesn't matter.
