TurboTax is not involved with sending the stimulus money. The IRS is still issuing the third stimulus payments. Since you are on social security, the IRS has your account information.
Keep in mind that if the stimulus was not issued and is then claimed as a Recovery Rebate Credit, then the funds are no longer protected from government or other debts. For more information, see: Recovery Rebate Credit — Topic E: Receiving the Credit | Internal Revenue Service
The green dot card is handled by the Santa Barbara Tax Group, but it is good that you still have the card and have access to it if needed later.
