I already e-filed my 2024 1040-SR and did pay the IRS the whole balance using my bank account during e-filing. After reviewing my printed copy of the 1040-SR I discovered to my surprise a Penalty/Interest charge of $103.0 on my 2024 Federal Tax Return Summary. While preparing my 2024 taxes on TurboTax I was not informed or directed that there was an issue with an estimated tax penalty. In 2023, I e-filed my 1040-SR and paid the whole balance on time too, so I don't know where the tax penalty on my 2024 1040-SR came from. Any advice what I should do? Thanks.
