Can I delay my payment for turbo tax because I'm waiting on my refund

Did you get an  email to pay?   If the IRS is still holding your refund 36 days after your original estimated refund date they will ask you to pay the fees or they will debit your bank account. See, What happens if the IRS reduces my refund.

You can choose to pay TurboTax with your refund or you can pay TurboTax with a credit card or bank authorization.

 

TurboTax accepts credit, debit, and prepaid cards with a Visa, MasterCard, American Express, or Discover logo. Like many other U.S. online merchants, we can only process cards with a U.S. billing address.

 

A second option is to pay with your federal refund, also known as Pay With My Refund (charges may apply).

We're unable to take check, money order, or cash payments.

1. Open or continue your return.
2. Select File and Start next to Step 1 Review your order.
3. Choose how you'd like to pay and Confirm Payment.
