Submitted Timesheet With Wrong Date

Am running ERPNext v15.22.2 on Ubuntu v22.04.4. In a project subtask (child task which reports to a parent task), one timesheet with multiple days entries has a date which is supposed to be 1/9/2024 but was entered as 9/1/2024. I did not catch this before I submitted the timesheet for billing which, the timesheets were billed. I cannot seem to find a ledger / journal which shows the entries.
Question: Where to go to correct this timesheet entry to reflect the correct date?
