First year filing, filed 2023 and used NETILE. Said I needed a CRA account, which needs previous year's return gross.Anyway to change from NETFILE to paper so I can file?

My return is locked. I can print personal copy but they specifically say not to sent to the CRA. Or I can refile it.
Anybody know how I can change my method of filing or how to get past needing previous year's return for CRA account?
