What versions to use? Married couple - one with simple taxes, the other self-employed & with a T4

Hi, I have simple taxes (although this year I have to include what I paid back for the HBP program), but my husband is self-employed and his taxes are more complex (plus he has a T4 for a second job of his).

I'm just wondering what versions we should be choosing. Do we each need a different version, or do we choose one and both use it? We have never used TurboTax before. Thank you.
