If you have TurboTax Business, which is what you would need to create an S-Corp return, then there is no additional charge to create a Trust return (Form 1041). If you filed personal returns and claimed your S-Corp income reported on Form K-1, it depends upon whether you used Online or Desktop. You can only create one return (federal + states) for each Online account. Creating an additional personal return for your son would require creating an additional account and paying again. If you use TurboTax Desktop for your personal return, you can create as many personal returns as you would like. For additional information on the products see the following:
