If you are preparing your returns together, you will both be using the same version of TurboTax and will both be charged the same price.
If you are using TurboTax Online, your wife will need to use the Self-Employed version.
If you want to use TurboTax CD/Download (for Windows 10/11), then we recommend using Home & Business, but you can use any version. They all have the same forms, but Home & Business provides more guidance in the Self-Employed/Business section.
