Investigating further, the EULA on the TurboTax website differs from the EULA contained in the software. In the 2024 software the EULA says "your," not "your own." In all cases, the EULA mentions filing "federal returns," which actually seems to imply that "your" or "your own" includes more than one individual. So I guess it's not that clear after all. There doesn't seem to be any explicit definition of "your" or "your own" in the context of this EULA.
