Yes, of course you can use your desktop software to prepare a 2022 return for your parents. You will not, however, be able to e-file those returns. E-filing is closed now for 2022 returns if you are using the desktop software. Any returns you prepare using desktop software for the 2022 tax year now have to be filed by mail. If you really are asking about using the 2023 software next year to prepare multiple returns---yes, you can prepare and e-file up to five federal returns for yourselves or other family members, etc.
