the entire balance due needed to be paid on or before the original due date of 4/15/2025 unless you qualified to pay later due to qualifying for disaster relief. late payment penalties are 1/2% a month for each month or fraction thereof that it's late. interest is added daily. the sooner you pay the sooner the penalties and interest will stop. if you are unable to pay you can apply for a payment plan. the penalties and interest are computed on the unpaid balance not your tax liability.

Turbotax does not compute these penalties and interest.
