I have to pay immediatlley ?

Did you choose to have your TurboTax fees deducted from your federal refund?  Is your refund taking an unusually long time to arrive?  Or was your refund seized to pay a debt you owed? if so, you signed an agreement that says TT can withdraw its fees from your account.  TurboTax sends  several emails to you before they take the money out of your account.

TURBOTAX SAYS:

How do you justify debiting my account?

The provision is spelled out in the Pay With My Refund Agreement, which you agreed to when you opted to pay with your refund.

In addition, by clicking the "I Agree" button below, you electronically sign and authorize Intuit (through its third party processor) to debit the TurboTax Fees, Additional Products and Services Purchased and any applicable sales tax from your bank account number identified in the Agreement below, in the event that you do not receive a tax refund that is sufficient to pay for them.
