I still haven’t received my stimulus check, is there any way we could find out why?

TurboTax has no control over your stimulus check, nor can TT track it for you or tell you when the IRS will issue it. Refer to the sites linked below:

You can call the IRS hotline at 1-800-919-9835 to get updates on your stimulus payment.

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.

Not really at this late date ... however if you don't get it by the end of the year you can get what you qualify for on the 2020 return you file next year.

did you check at the IRS website?

otherwise, there is a 'settle up' section as part of the 2020 tax return and the stimulus should end up on Line 30 of Form 1040.
