Mojave installation problem

When I try to install 10.14.1 today, I followed the instructions as per the App Store and got the following when I clicked onto my hard drive to install "This disk is used for Time Machine backups". There are no other disks attached to my iMac, late 2017 Retina 5K 4.2Ghz. I am currently running 10.13.6.

iMac (Retina 5K, 27-inch, 2017), macOS High Sierra (10.13.6)
