Hi,
I accidently claimed the unused tuition and education amounts from previous years for 2022 tax year. So, after notice of assessment, I tried to cancel the unused credit claim using Refile but there are two issues:
1. No update on Student Summary. It shows "0" on unused tuition and education amounts from previous years
2. Can not upload to CRA with "CRA Result Code: 603"
I am wondering whether this item can be changed and if changeable, what happened to my file.
Thanks,
