If you already deducted these expenses as part of your net research grants in Box 104 of your T4A, please return to the T4A (Under Income > T-Slips) and add back the expenses you entered on the Tax Saving Opportunity page to the amount in Box 104 so that they are not deducted twice. It is not currently possible to return to the Tax Saving Opportunity question once an amount has been entered there.
