Tax Reporting from Paypal G&S

I have two questions:

1) If someone paid me $610 for some concert tickets on PayPal G&S and I recieved $595 after PayPal charged a seller fee, do I still have to report it.

2) What if someone else paid me through Vemno G&S and the PayPal + Venmo adds up to more than $600 together but less than $600 each. What do I do then?
