Can I file another return that is my son's off this account? He would use the 1040ez.

[Opus 17]

Each Turbotax Online account can only file one tax return.  If you need to file more than one return, you need to create additional accounts.  You can have multiple accounts linked to one email address for notifications, just with different user names.  Go to the account sign in page but choose "Create a new account."

Unless you qualify for free filing, each account has a separate filing fee.  

If your income is less than $33,000, you can file using the TaxFreedom edition, which includes complicated forms not normally included in the "regular" free version of Turbotax. The IRS requires it to be a separate web site. https://turbotax.intuit.com/taxfreedom/  

You must create a different account to use TaxFreedom, you can't use your existing Turbotax account.  You will need to start over from scratch.  You may also need to clear your browser cache and cookies before logging in. https://ttlc.intuit.com/replies/3491786
