Trial Balance for 000000.000000 USSGL, but no corresponding Journal

In a Federal R12.2.10 PROD instance, the Trial Balance displays a USSGL account '000000.00000' for OCT-FY-25, but no corresponding/ expected journal for $212K. The TB was also run for AUG-FY-24, SEP-FY-24, ADJ-FY-24, but no USSGL balance was present. A query on GL balances displays this GL CCID and balance for OCT-FY-25, but no GJ line, journal, or batch corresponds. The GL Account Inquiry form displays the balance, but no journal information.

Any thoughts would be appreciated.
