I copied and pasted the below section and made what I quoted earlier in red.
==================
You must use the edition of TurboTax Desktop for the year you're amending. For example, you must amend your 2024 return in TurboTax Desktop Business 2024.
Amend a return for an S corporation
- Open TurboTax.
