Deferring medical expenses on T4

[nabeelj]

I have some medical expenses on box 85 of my T4, which I do not want to claim this year. This is because it's more advantageous for me to claim medical expenses for the period Dec 2021 - Nov 2022 instead, which would include most of the expenses on my T4, as well as some other expenses.

How can I tell Ufile not to attempt to use the amount on box 85 on my T4? I tried doing "Claim $0" for both my spouse and I, but it still tries to use the amount for my spouse.
