Can you edit your forum profile to show which edition of Z18 you have installed. i.e. Pro, Core, Lite, Education. That extra info will help us help you.
You asked about equivalent to Windows Restore in your other thread. Have a look at Timeshift at some point, but take care how much drive space gets used. Perform a search here on the forum for "Timeshift" and see what is being said.
I hope you did not choose to do encryption this time. It over complicates things and is unnecessary for "normal" users.
You should download the unofficial manual for Z18, authored by @swarfendor437 when you have the time. I think this thread points to the source: Unofficial Manual for Zorin 18 Core Mk.II (based on r.3) - Bitstream Vera Sans editions in .docx and .pdf
