We have a number of google cloud storage transfer job that sync from aws s3 buckets to google buckets. I am assuming that they are using https to transfer the data but where can I get a confirmation that they do. Where can I get information about minimum TLS version used in these transfer jobs.

Here is a lot of info on how Google uses encryption to protect your data: cloud.google.com/security/encryption-in-transit - maybe there's something in there that answers your questions/concerns. (I did not read it all) – Tobias K.

Regarding the Cloud Storage TLS, in this document you could find the TLS information for the gsutil commands which requests are done via the JSON API. These requests are via HTTPS only, and are used within the cloud console too.
