Prepare a second, separate return for a deceased person under my TurboTax Premier 2024?

I have purchased and used TurboTax Premier 2024 for my personal joint return this year. Now I need to file my late father's final return as the executrix of his estate. Can I use that purchased program and license to create that second return (his) in my Windows PC?  Would I need to purchase a separate TurboTax Premier 2024? If so, could I run both on the same PC?  Thanks for your advice on this.
