Why is my log file so massive? 22gb. I am running log backups
You are confusing allocated space with used space.  After running the backup use this query to see the difference between allocated and used space. 

select file_id
, type_desc
, name
, substring([physical_name],1,3) AS [Drive]
, physical_name
, state_desc
, size / 128 as 'AllocatedSizeMB'
, FILEPROPERTY([name],'SpaceUsed') /128 AS 'SpaceUsedMB'  --Addapted from https://sqlperformance.com/2014/12/io-subsystem/proactive-sql-server-health-checks-1
, (1- (FILEPROPERTY([name],'SpaceUsed') / CAST (size AS MONEY))) *100 AS 'PercentFree'
, growth / 128 as 'GrowthSettingMB'

 from sys.database_files
 order by type_desc Desc, name


You can use the GUI to shrink the log file by changing the 'Initial size'



If you are having troubles shrinking the log, even when it looks mostly empty see my post here
