My tax refund amount went down when I added my tuition details from my T2202. I looked online and apparently it's because of a glitch with something called the WITB?

Hi,

Possibly because before entering your information from your T2202 slip, you were eligible for Canada workers benefit (refundable tax credit). But after entering your information on your T2202 slip, you were not eligible. You can click on link below to see the eligibility of this credit:

Thank you!
