We got charged a 54.00 convince fee by the IRS, I did not see this anywhere when I filed my taxes on line with TurboTax. Is this something new?

Did you use a credit card to pay your taxes?  The government is prohibited by law from paying the credit card company's service fee.

Pay Your Taxes by Debit or Credit Card | Internal Revenue Service (irs.gov)

If you paid federal taxes owed by credit card there is a convenience fee as posted on the IRS website - https://www.irs.gov/payments/pay-your-taxes-by-debit-or-credit-card

Otherwise, where are you seeing this convenience fee from the IRS?
