I have noticed when my taxes for comparison were posted from 2023 and 2024 there were some important boxes not listed in 2023 but were in 24 can I redo my 2023 return?

Example my cpp wasn’t entered and a couple others

Troubleshooting

Yes, you can. This TurboTax FAQ tells you how to make changes to a return you’ve already filed: I've filed my tax return. Can I still make changes?
