I am trying to file for a prior year and filed through Turbo Tax desktop but didn't get a form 1120-s. Where is that generated from?

If you were a shareholder in an S corporation, you would have (or should have) received a Schedule K-1 (1120-S). 

The K-1 (1120-S) is generated in the process of preparing Form 1120-S for the S corporation.

If you have a business that has incorporated as a S Corporation then you need to file a Form 1120-S.

You will need to purchase the TurboTax Business Edition to complete and file the 1120-S.  The Business Edition can only be installed on a Windows based personal computer.  The Business Edition does not support a personal tax return, Form 1040.  The Business Edition will also generate a Schedule K-1 from the S Corp that you report on your personal tax return.

Go to this TurboTax website for the 2023 Business Edition - https://turbotax.intuit.com/small-business-taxes/cd-download/

To complete and file a prior year (2022 thru 2020) tax return using TurboTax you would need to purchase, download and install on a personal computer one of the Business desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A prior year tax return can only be printed and mailed, it cannot be e-filed using TurboTax.

If you need to prepare a 1120 S corp return you need to buy Turbo Tax Business which is a separate program from Home & Business.  Turbo Tax Business is only available for Windows and not Mac and not Online.

You can buy the current Window's Desktop program here…..

I'll add that if you do need to file a Form 1120-S for a previous year, you are late and will face penalties for the failure to timely file.

As a result, you should seek guidance from a qualified tax professional.
