I'll assume you are using Online TurboTax and not the Mobile App.
The My Account button was removed about 4 years ago. The website was redesigned back then. You must be looking at old info.
Here's how to get to the Tools menu:
Log in and open your return (if not already open) and go to the left menu column. In that left column you should see the tab TAX TOOLS. Click it and you'll see a submenu.
What are you wanting do with Tools?
