How can I find out who sent money to my Email?

To learn about Apple Cash transaction info, check here: See your Apple Cash transactions - Apple Support

I usually suggest turning off automatic acceptance of Apple Cash payments, because of a fairly common scam. In one version of the scam, the scammer sends cash using stolen payment info "by accident", and then requests or demands some or all of the payment be returned. When the original payment gets clawed back by the banks, you will have then lost any refund you provided.

Where are you seeing this? Screenshot may be used as long as it does not contain any personal information.

Wait, these transactions occurred almost a year and a half ago. Why are you asking abut this now?
