After you file

I'll just explain the process I did:

I made a new account and started a tax return (it was the first time I did on my own) - I was asked if I wanted to link my CRA account for auto filling - I couldn't as the CRA account needs a phone number confirmation and at that time, I did not have my phone. Since, I could not access my CRA account, I left the NETFILE access code blank as it was not mandatory - it just said leave blank if you do not want to enter the details. So, I moved on, gave all my information, filed the taxes, paid for it and got a 2023 tax return pdf. I thought everything was done. 

After coming back to Canada, I checked my CRA account and it stated that 2023 taxes were not filed yet after which I sent this message on turbo tax. What should I do now ?

I also can't access the tax return file anymore.
