You have to respond that your re not in Canada. It will not affect your application, but you will not be given a COPR as for that you have to be in Canada. Once you are back, you can inform IRCC and your cOPR will be issued.
Alternatively, if you intent staying in your home country longer, you can inform IRCC of change of address, and as and when things open, you will be asked to submit your passport for COPR and PR visa (if not from a visa exempt country.)
