Hi olga5, we're happy to have you here as a part of the Community!
QuickBooks Online is unable to file a Form 1120S, however we do have TurboTax and ProConnect which can be used to both generate and file this form.
You can use this link to reach our TurboTax Support:

Please keep me updated on the situation, I'm here to help if you have any questions. I'll look forward to hearing back from you.
