How to edit a field

[Raymond22]

I'm almost done, ready to Netfile when I realize that my wife's return has an entry for medical expenses at line 33099! I didn't claim, she didn't claim any medical expenses. In the interview set-up, the medical expenses box was left unchecked on both returns.  How to edit line 33099 and adjust to $0.00?

Thanks

please ignore my post on medical expenses and "how to edit a field". The amount that I was trying to delete is actually from a box on a T4A.  My apologies.
