Get your taxes done using TurboTax

Please explain where that step in the process is regarding "have IRS calculate any penalty / interest". Is it under "deductions and credits" or "other tax situations"? I updated the date of the payment for the payment included with my Form 4868 to May 1, 2025 and I don't see any change in my refund or balance due. So, it looks like TurboTax may have been updated to permit an extension and payment by May 1, 2025 for Florida residents. But if I still ned to flag the return to have the IRS calculate any penalty/interest, I need to know where that is. TIA!
