I want to make a copy of my 2024 return to test the impact of some business decisions I could have made last year. My 2024 return has been filed and accepted. I don't want to amend my return for filing. This is just for personal use. If I duplicate my 2024 return and rename it, it still will not allow me to make changes because it has been filed. I have done this in the past, but it does not seem to be allowed now. Any ideas? Thanks!
