You cannot install two different personal TurboTax desktop programs for the same tax year on the same computer because it can cause conflicts. The software is designed to handle multiple returns (up to five federal) in one installation.
However, you can install TurboTax Business along with one other personal version, such as Premier, or Home & Business.
If you need to prepare more than five federal returns, you must use a different computer, use the online version, or file by mail. However, keep in mind that the IRS limits individuals to e-filing a maximum of five tax returns per software license, account, or email address. This is done for security and identification purposes.
