The highest version of iOS you can run on an iPhone 6 is iOS 12.5.5. If you are looking for anything higher, iPhone 6 release almost 8 years ago is lacking the hardware required to run the newer iOS versions. If you need the newer iOS versions, then you'll need to purchase a newer, more modern iPhone at this point.
An iPhone 6 cannot update past iOS 12.5.5. You need a new phone.
