How do I delete a transferred prior year completed tax return?

[taxhard47]

I'm using 2025 TurboTax Online Deluxe. I just started using it.

It offered to transfer information from a prior year's TurboTax tax file. I was my <my chosen name>.tax2024 file.

It filled in a bunch of stuff on my current year's Personal Info section, for example.

At the bottom of my Tax Home webpage, I see "Your tax returns & documents" and then a blue oval "2024".

How can I delete this transferred prior year completed tax return? Not just individual forms within the return (I tried but some don't seem to be delete-able).
