Paypal needs to confirm tax info?

Got a payment from dscout and then a message from Paypal saying to confirm my ‘tax information’ which is my SSN (US). They say they need to send me a 1099 for payments over 600.00

This seems legit, but I’ve never made more than a few hundred dollars from Prolific in a year, so this hasn’t come up. Just want the wisdom of this sub before entering my SSN on Paypal. Thanks!
