do you add a fee for me using my credit card to pay for my product?

TurboTax does not charge to use a credit card, but there is a convenience fee, which is charged by the payment processor.

Can I pay my IRS taxes with a credit or debit card?

Yes, through a third-party payment processor. However, there is a convenience fee, which is charged by the payment processor.

If you owe the IRS and you're e-filing, select the option Charge my credit card when asked how you want to pay your federal taxes in the File section.

The credit/debit card payment option is only available in TurboTax if you e-file your federal return. However, there is a workaround if you're paper-filing your return.

Tip: Instead of paying the convenience fee for debit card payment, consider direct debit, which is free

There is no additional charge for paying your TurboTax fees using a credit or debit card.

As I stated in my answer, there IS a convenience fee charged to use a credit card:  a 2.49 percent fee is charged when you use a credit card to e-file your return.
