Extract month name and year from timestamp to same column

I have a timestamp in the format: July 13, 2020, 6:07 PM

I would like to only keep the month and the year for my records. Ideally in the format: July, 2020

I've attempted the following that creates a column for each:

select 
        count(distinct my_id),
        count(distinct my_loc),
        to_char(created_at, 'month'),
        date_part('year', created_at)
from acc_facts
group by created_at

The output is something like this (in 4 columns):

86 2 may 2,020

Could it be possible to get (in 3 columns):

86 2 May,2020
