Hi, unlike Medicals, Biometrics cannot be done upfront. An applicant has to wait for IRCC to send an official Biometrics Collection Letter and the letter will include applicant's name, UCI, Application number with instructions on how to get Biometrics done. I remember when I did mine recently at a Service Canada office, the agent gave me a Reference number and asked me to keep it safely in case IRCC may ask for it. If I may ask, where you given a number when you did yours. It is strange if IRCC cannot locate your Biometrics, as you know these are valid for 10 years. If an applicant is outside Canada, like in your case, you would do yours at a VAC centre, while if on Canadian soil, it is done at Service Canada. In case you did your Biometrics at VAC Centre, I suggest you contact them, I am sure they will be having your records on file. The fact that you had already done your Biometrics, you should be able to view your Biometrics information in your GC Key account.
