You don't cancel the returns. You have two choices-
1-Amend your personal. This new amended return will supersede the 1120S returns that you have filed and the IRS should disregard them. Just make certain that you have entered the EIN for your business into the schedule C.
2-Paper file your 2022 return along with all of the necessary paperwork to qualify you for your S-election (had you filed it on time) and a letter explaining your situation. Then wait for the IRS to contact you about your 2021 and 2022 filings.
I would do the second, but if you're determined to amend the returns then TurboTax can do it. Just add the schedule C.
