What is the additional $40 processing fee for?

[DoninGA]

When you selected to have the TurboTax account fees paid from the federal tax refund, instead of using your credit card to pay the fee, there is a $40 third party service charge for this option.

See this TurboTax support FAQ for removing the pay with refund option - https://ttlc.intuit.com/turbotax-support/en-us/help-article/intuit-account-billing/remove-pay-refund...
