Last year I made a mistake in last year filing, I had to pay back 1,664. How do I avoid that this year? It was the workers benefit

While I was filing my tax last year it said I was qualified to get the CWB since I made very less money in 2024. The thing is I got the money and a few months later by October they reassessed and asked me to pay back 1,665 because since I was a student I was no longer qualified for the benefit and I want to avoid that this year’s tax.
