Hi debsw1,
Assuming you're using TurboTax Online, you'd type "T777" into the Search bar to start the T777 topic. Follow the prompts. When you see the page called "Employment expenses profile", make sure to select the checkboxes that apply to you. Then, you should see the forms where you enter your expenses.
If you see the GST/HST rebate page even though it doesn't apply to you, simply leave it blank and continue.
