TurboTax has NO control over your stimulus check, nor can TT track it or tell you when you will receive it. The IRS will use the same banking information for the 2nd stimulus that they used for the first one. If that account (or card) is closed then the stimulus will go back to the IRS and they will mail you a check. See this information from the IRS:

If this goes "sideways" on you, you can still get the stimulus money on your 2020 return. Under Other Tax Situations you will be asked about the stimulus money you received.
The stimulus check is an advance on a credit you can receive on your 2020 tax return. If something went wrong or you did not get the stimulus check this year, you can get it when you file your 2020 return in early 2021—if you are eligible.It will end up on line 30 of your 2020 Form 1040.
