IRS Failure to file fee (Days of Interest charge don't match my submission)

Hi all. I submitted my 2019 return ~2 weeks late (submitted 8/2 | accepted 8/5) per TurboTax. However, I just received an IRS failure to file for the full 30 days (8/15). How can I argue against these incremental August fees? The respective IRS site only offers ways to pay the existing fine.
