Is Form 502UP underpayment already accounted for when filing Form 502X amendment?

I'm filing a federal and state 2022 amendment using TurboTax desktop 2022 to generate the required forms to mail in.

• For the state amendment a 502UP underpayment of estimated income tax is created showing interest owed on line 18 of $116.
• Checking my original 2022 tax return filed it includes a 502UP with the same line 18 $116 amount.
• However the 502X amendment created with the TurboTax desktop amend feature shows no value owed on lines 26, 27, and 28.

Do I need to pay the state $116 or has this already been factored into the amendment based on the original 2022 taxes filed in which I paid the "tax due" amount in full directly to the state? It seems based on Brave AI and Grok's tax doc and forum searches the $116 has already been factored into the originally paid state tax due.

Much appreciated!

Thanks to a TurboTax expert they informed me that the Form 502UP does not need to be included the amendment because Form 502X does not change the amount owed shown in lines 26, 27, and 28.
