You are welcome. Honestly, I'd recommend saving it on a USB drive as well and keep it in a safe place. But if you prefer OneDrive, there are security measures that you can put in place to help protect it there. See here for those security measures OneDrive file security and I would strongly recommend using those, if at all possible.
You don't want to risk your personal information getting into the wrong hands. Another option you may also want to look into is third party programs that offer encryption of OneDrive files for added security. You can never be too careful. Just make sure to do thorough research on those third party programs, if you decide you want to add encryption.
