Found this on Activsion website:

"The only way to play with your friends is to send or receive an invite via the Xbox LIVE or Steam dashboard. Make sure you create a Private lobby to ensure that only your friends can join.

Note: Players cannot join a Private match in the PC version of TMNT: Out of the Shadows at this time. We apologize for the inconvenience and hope to have this resolved in an upcoming patch."
