Do you mean you uninstalled? OneDrive is a feature you cannot really removed from your Microsoft 365 subscription, so not sure what you meant exactly by deleting it from your account.
If you meant uninstall, you can install it back.
You can download it from here: https://www.microsoft.com/microsoft-365/onedrive/download
After that, just install it and sign back in.
