visit the IRS at https://www.irs.gov/filing/free-file-do-your-federal-taxes-for-free
to find truly free filing. Note that some include free state as well.
Otherwise, If you have to file a state return, and don't want to do that yourself, you will need software that you pay for.
If you choose TurboTax (I don't know why you would) you must create a new account.
If you sign in with your existing account, you'll be back in the same place you're trying to escape.
