However, I am a bit confused because my understanding is that S-Corporations typically file their returns by March 15 of the following year. This makes me wonder how I could file Form 1120-S on November 15, 2024, instead of  by March 15, 2025.

The 1120-S is due 2.5 months after the end of its tax year.

If the corporation existed the entire calendar year, the end of its tax year is December 31st.  The due date is 2.5 months after their tax year ends, so the due date is March 15th.

If the corporation ended on August 1st, the tax year ended in August.  The due date is 2.5 months after their tax year ends, so the due date is November 15th.

It is usually ideal to file an extension when the corporation dissolves so the actual filing can be done once the new year's software is ready.
