How do I add another taxpayer to my 2025 TurboTax desktop account?

[xmasbaby0]

When you have desktop download software you can prepare and e-file up to five federal returns and the state returns that go with them.  You do not add users to your "account" to do that.   You open up your software from your own hard drive, go up to "File" on the top of your screen, and click "New Tax Return" in order to prepare a return for another family member.

To start another tax return -

Click on File at the top left of the desktop program screen

Click on New Tax Return

Only the purchaser of the software can install the TurboTax software on up to 5 computers that they own.
