It is so frustrating that your instructions here is not consistent with the turnbox.com at all.
1. My account is only displayed/showed up in the bottom portion of the whole screen after I logged in.
2. After clicked My account, there are only 3 items showing up, you can't find "Tax Tools" item at all
3. Only when you click the 2nd item: View Order Summary under My Account, you would find, suddenly all the other menu items displaying up from the left side of the screen, joining the existing menu times, like Tax Home, documents, etc.
I am an IT guy, I totally disagreed with such a design. I even wonder the purpose of such design. I have been using Turbox tax over 15 years (?). It is the first time I thought of changing another tax tool provider.
You are responding to a post that is over 5 years old, so the program has likely changed in that time frame.
