Hello @writerchick324,
Let me add a few things about your Intuit and TurboTax account and how you can use it.
When you purchase and subscribe to any Intuit products, online, or in a software/app, you'll only need to use one login credential (a username and password for all products). This is to ensure that you can access your account information, business or personal, so you can prepare your taxes easily.
In addition, here's an article you can read to learn more about your account information (go directly to paragraph 4 under What is an Intuit Account?): Manage your Intuit Account online.
You can also visit and learn more with the steps about how you can create a user for your online account: Create an Intuit user account.
If there's anything else that I can help you with, let me know in the comments below. Stay safe always!
