How to create new CRA account after SIN changed if I don't remember my last line 15000 in 2025?

Hi! I became a PR last month and got a new SIN, and when I tried it login to CRA using my old credentials, it says the login is invalid and I need to create a new CRA account. However, when creating a new account, it asks me for the line 15000 on the my 2025 tax return. Problem is, I don't remember and I didn't save a copy of my last NOA. I only have the 2024 one. I thought it would be just be saved on my CRA account, so I didn't think to save a copy on my device.

So now, I don't know what to do. Is there another way for me to see my NOA?
