What should I do if I made a tiny mistake in my application form?

[hisense]

In the Schedule 1 Background / Declaration form, Question 9 :
- Previously sought refugee status in Canada or applied for a Canadian immigrant or permanent resident visa or visitor or temporary resident visa?

I answered NO, although I'm now studying in Canada with Study permit.

I applied last week and still waiting
Could you please what should I do in this case?

Note: I submitted my application two weeks ago and still waiting for an acknowledgment and my file number.

Thanks in advance.
