WAL space Issue

I am having issues with WAL directory. I have the tsdb retention size to 175 GB, but the WAL size is increasing huge. now its 281 GB.

ExecStart=/apps/prometheus/prometheus_server/prometheus
–config.file=/apps/prometheus/prometheus_server/prometheus.yml
–storage.tsdb.path=/apps/prometheus/prometheus_data
–storage.tsdb.retention.size=175GB
–storage.tsdb.retention.time=180d

du -sh wal
281G wal

Is there any setting I can make to control the WAL space?

Prometheus version is
