For 2024 I had capital gains and prior losses. But I do not need to use the losses, tax=0. How do I remove the prior losses without an override?

In Forms mode, you can go to the LOSS worksheet and change the amount that is being claimed in 2024. 

In EasyStep mode, you can search for "Loss". Then check off whatever you need and continue through the pages to get the option to change what is being claimed for 2024.
