If you enter investment expenses and they exceed your investment income, then this amount will carry forward. However, if in your case, you don't have any investment income, I would recommend consulting with the CRA to determine if you can still call the investment expenses.
If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
