Get your taxes done using TurboTax

Please explain more.  What is the problem?  You have to sign into or create a Turbo Tax account this year.  Go back and read the first part of that article for why do I need to sign in to an Intuit Account this year?

I guess you could have created a new account if you wanted to keep the Business program separate from your personal account.   Otherwise call support and ask them
