if I'm filing a standard w2 why do I have to pay?

Do you have any other forms like a 1099?

To go back to the Free Edition or a lower version you can try to clear and start over.  But if you originally started in Free you might not need to clear it.

In the Turbo Tax Free Edition, information that you can enter is limited now.  Why do I have to upgrade from the Free Edition?

Or go to the IRS Free File programs

It could be this common reason.

It might be giving you the Savers Credit on Schedule 3.  If you just want to forget getting that saver credit due to the upgrade to Deluxe, you can tell the software in My Info that you were a student and it will disqualify you for the credit and let you use the Free Edition.
