If you need to prepare a Form 1120-S for an S corporation, you need TurboTax Business (link below) which is not available online or for a Mac; it must be installed and run in a Windows environment. Further, TurboTax Business can only be used to prepare income tax returns for entities; it cannot be used to prepare an individual income tax return (e.g., Form 1040).

Finally, if you are not extremely familiar with the rules and regulations that relate to S corporations, you should definitely seek professional tax guidance and assistance with return preparation rather than attempting to do it yourself.

If you elected S-corp status for your LLC (to be taxed as an S-corp), then in either case, you'll need TurboTax Business to file your 1120-S return. And the corp return was due 3/15/19 unless you put it on extension AND if you are not familiar with filing an 1120-S then I highly recommend you seek local professional assistance ... the LIVE help in the Self Employed program will not help you with this return or other program.
