My husband hasnt received the stimulus check ($1400), Can Turbo Tax help us?

The recovery rebate credit is only for the 1st or 2nd EIP payment --- not the 3rd payment of $1400.   There is no place on a 2020 return to enter anything at all about the 3rd stimulus payment.   That 3rd payment is issued separately by the IRS.  Did you file separate returns?   You mentioned that just your spouse did not receive it----did he file a 2020 return?   Has it been processed?   The IRS often releases the $1400 after they process the 2020 return.   If they do not send it then it can be reconciled on his 2021 tax return next year.

TurboTax cannot track your 3rd stimulus or tell you when it will arrive.  The IRS is issuing 3rd stimulus checks on its own timetable.

You can use the IRS Get My Payment site to see what is expected for your 3rd stimulus check:
