If you have an S corporation, you need to file a Form 1120-S for that corporation.
See https://www.irs.gov/instructions/i1120s#idm139641016872208
TurboTax Home & Business cannot be used to file an 1120-S. The TurboTax product that can be used to prepare and file an 1120-S is TurboTax Business (link below).
