You should consult with a tax professional for guidance and/or return preparation in this matter.
The S corporation returns are very late and there could be substantial penalties for failure to file. The return is generally due by the 15th day of the 3rd month after the end of the corporation's tax year (typically, March 15th for calendar year corporations).

You can use TurboTax Business for tax years 2017 and 2018, but each year is a separate purchase and you would also have to purchase the NY state return for each year. You are really better off allowing a tax professional to handle this situation.
