You cannot file a 1120S form and an individual tax return together. A 1120S form is for a SCorp which is considered a separate legal entity, therefore it requires its own tax return. For each of the stockholders of the SCorp, a K-1 form will be generated when the 1120S return is prepared. The K-1 form is for each of the stockholders to report their share of the income and expenses of the SCorp when preparing their individual tax returns.
To create and file a 1120S form, you will need to use TurboTax Business (CD or download.
