Why such a big price tag for "Networking Traffic Egress GCP Replication Within Northern America"?

I wanted to move a 1 TB table to archive storage. The method I used: through the Google BigQuery interface, I use the Export to GCS option. So according to my calculations, it should have taken ~ $ 20 for the transfer, but it took $ 240. Can you tell me why they put up such a price tag? As a result, 37 thousand files were created.

That seems like a lot.  Sorry for the unpleasant surprise. When you look at the SKU-level breakdown of this cost in the "Cost table" view in Cloud Console, which SKUs account for most of the charges? What is the usage reported against these?
