Maybe you're not Signing In with the same account you used for your 2023 return. If you think this might apply, here's more info on How to Access a Prior Year Return, with a link to find all your accounts.
When you click on 2023 on the home page under 'My Tax Returns and Documents' you may need to scroll down and click on 'Add a State' to get back into your 2023 return.
