There is no need or reason to put another copy of the 2023 desktop software on your father's computer----and you would not be able to if you tried. If he already has the software downloaded/installed, then up to five federal returns can be e-filed using his computer and his software. Using his computer does not mean you will see any of his information or see his tax return. You can use his PC (or Mac) and launch his desktop program from his hard drive, then click "File" at the top of the screen. A drop down will appear and you click New Tax Return. You can then use his program to prepare and e-file your own return. If you do not want Dad to see your return, encrypt it and save it with a password (and keep a record for yourself of how to get to the return again someday). Your return will be saved on Dad's hard drive and/or any back up device you use like a flash drive. It will not be stored online in a TT account.
Seek a refund for unnecessary software you purchased. Maybe take Dad a pizza for letting you use his computer.
