You have to be inside of your return in order to see Tools under My Account. If you are still on the My Tax Timeline page, you will only see Account Settings and Save & Sign Out under My Account.
So if you are still on the Tax Timeline page where you see the orange Take me to my return button, click that button and then go to My Account and Tools and follow the rest of the steps below once you click on "TurboTax Online."
NOTE: EIC will be on line 66a of the 1040, and ACTC will be on line 67
