You only needed one version of the CD/download. You cannot install two versions for the same tax year. Each CD/download of the desktop software can be used to prepare and e-file up to five federal returns and can also prepare and e-file state returns. You can use the version you already have on your computer to prepare the return for your father or other family members. Even if he is not self-employed, you can use that version for any sort of income he received unless he has a business like an Scorps or Ccorps. If he just has W-2 income or retirement income, etc. you are fine to use the Home and Business software for his return. See if you can return the Deluxe--you do not need it.
