Maybe you can try the online results in IDP page. I could view mine online - online provisional results by IDP Australia.
Anyway, if this does not work, and you would really like to take a chance, the TRF number has a pattern:
YY CC XXXXXX LASF TTT G
Example: 19US001234EEPT300G
YY - year -> 19
CC - name of country where you took the exam -> US (in my case)
XXXXXX - Candidate number - provided to you
LASF - first 3 digits of your last name followed by first letter of your first name
TTT - test center code
G - G for general training; A for academic
This will be easy if you have taken an exam in your test center before or if you know someone who took the exam in the same test center. You can try this if you could not wait for your TRF to have a higher CRS for this Wednesday's draw. If you got it wrong, you can always decline the ITA so you could enter on the next draw.
Hope this helps.
