You need to free up more space.

How to free up storage space on your Mac - Apple Support

From: How to upgrade to macOS Big Sur - Apple Support

"If upgrading from macOS Sierra or later, macOS Big Sur requires 35.5GB of available storage to upgrade. If upgrading from an earlier release, macOS Big Sur requires up to 44.5GB of available storage. To upgrade from OS X Mountain Lion, first upgrade to OS X El Capitan, then upgrade to macOS Big Sur."
