Documentation is your friend - use either date_trunc with corresponding unit, or extraction functions (year, quarter):

select date_trunc('quarter', now())
    , date_trunc('year', now()) 
    , quarter(now())
    , year(now())

Sample output:

_col0 _col1 _col2 _col3
2022-07-01 00:00:00.000 UTC 2022-01-01 00:00:00.000 UTC 3 2022
