My Mac has 64 GB and it says that it does not have enough space. It requires 16 GB. I have enough space. How much more it needs?

FWIW, if you have 64 GB of available space on your drive that should be enough to upgrade. If you meant your Mac has 64 GBs RAM, that is immaterial.
If you need to free up space on the drive, See: Free up storage space on your Mac - Apple Support
It is generally a good computer practice to alway keep at least 15% to 20% of the Total Drive Capacity’s as Empty Space.
Allowing the computer to drop below these guidelines may eventually, cause unintended consequences.
The links below will assist in identifying what is taking up space on the Internal Drive and provide possible ways to remove data that is under the direct control of the User ( Home Folder ) .

Notation - If the user is using a cloning software like Carbon Copy Cloner - suggest tweaking the Safety Net Feature in this software. It may be making additional Snap Shots that are not being Cloned to the Eternal Drive. If this should be the case, these Snap Shot could be using additional space on the drive
The final word from Apple on Managing the " Other/ System Data “ Category
Other / System Data: Contains files that don’t fall into the categories listed here. This category primarily includes files and data used by the system, such as log files, caches, VM files, and other runtime system resources. Also included are temporary files, fonts, app support files, and plug-ins. You can't manage the contents of this category. The contents are managed by macOS, and the category varies in size depending on the current state of your Mac.
1 - The upgrade is 16GB but you need way more than 16GB, something like 45GB
2 - "Available" should be but in fact is not the same as "free".
Select your drive in the Finder and press Command-I.
What does it say in the info window?
It may say something like, for example:
Available: 30GB (73 GB purgeable)
The problem is that the system is not all that quick release that purgeable stuff. This may be local Time Machine snapshots, or stuff that you deleted but the OS did not mark as free.
What is the output of the following command in Terminal?
tmutil listlocalsnapshots /
Thank you for your response. I was able to upgrade last night. I am sorry, but I could not let it go (ADHD). I used an external hard drive and copy all the big files to it, and then deleted the HD. I do have a question though. Can I get an external hard drive and then make it an extension of the main HD? Thank you for your time.
Sincerely,
Jack
