Time Machine has no HD available disk

I accidentally removed my Macintosh HD option from available backup discs in Time Machine. I want to put it back on the backup disc list so I can continue backing it up but can not figure out how.

iMac 27″ 5K, macOS 10.15

I'll try to help you, Camis90. From the Time Machine menu which looks like a clock, Open Time Machine Preferences, or go to System Preferences, then Time Machine, click on " Select Disk/ Select Backup Disk" or "Add/Remove Backup Disk", and then "point" it to the Disk you want to use. then click on "Use Disk" . You may wish to turn on Encrypt Backup Disk, and that's it
