It's saying that the return has already been sent by Netfile, so you can't send it again. You would have to Refile using your original return file.

Am I correct in understanding that I need to fill everything out again? How do I do the following: "In Return Manager, select ReFILE beside the filed tax return you want to adjust." I can't find these buttons.

Have you used TurboTax Online Version or TurboTax Desktop Version? You can make changes to a filed tax return by filing a T1-adjustment. The CRA requires that you wait until you’ve received your Notice of Assessment (NOA) before filing an adjustment. In many cases, the CRA will catch the mismatch and automatically adjust your return for you.

For step-by-step instructions, please follow this TurboTax article:  I've filed my tax return. Can I still make changes?

I used Turbo Tax Online version. My question is that all the information concerns the situation when you have already filed a declaration and want to make changes to it. In my case, the "continue" box is active on the page, but I cannot finish filing the declaration, I cannot make changes to it either. In the CRA personal account, it is visible that the declaration is missing. This is the problem.

This message is generated by CRA. It's saying that the return has already been sent by Netfile, so you can't send it again. You would have to Refile using your original return file.

Are you sure you are using the correct tax year to file your return?

Yes, that's right, thank you. I can't start processing the tax return for 2024. I don't understand how to do it. I click on "start new return",but the program transfers me to 2023. How do I process the tax return for 2024?
