I need to amend Form 1040-X to correct line 16 before I submit. Turbo Tax is not indicating a credit for the amount previously paid. How can I correct this

I paid underpayment penalty for 2023 taxes. Used annualized method in amended return to correctly calculate underpayment penalty. Turbotax is not indicating my 2023 original taxes owed as payed. I am due a credit now due to a lower underpayment penalty
