You cannot upgrade in the Freedom Edition.

You must start again here:

Note that TT Freedom is different from TT Free.

You should be able to upgrade from Tax Freedom to Deluxe or higher.
While going through the Freedom Edition if you enter any information that causes ineligibility you will be asked to upgrade to Deluxe and it will transfer you to Turbo Tax Online.

But currently there is a looping problem with Tax Freedom

Here’s what one person found......
From TurbotaxFreedom, you have to click on "FILE" - there is no "UPGRADE" option. Then you get the message that you aren't eligible and there is a "Choose TurboTax Deluxe" button (as well as "Exit to IRS.gov")

All the TT answers say this cannot be done:

That second link says yes.

I thought that because of the "Chinese Wall" between Freedom and the other TT products, the user needed different ID's.
