"The client"? Are you a tax preparer? You cannot use TurboTax to prepare tax returns for clients. TurboTax is only for do-it-yourself consumer use and cannot be used by paid preparers. Intuit (the company that makes TurboTax) has three tax software product lines for professional preparers: ProSeries, Lacerte, and ProConnect. You can find information about all three product lines at the following link.
