Nobody knows for sure, but most likely she has been handed over to the Homeland. The last time we saw her, the three were heading there. She said that Reiner and Bertolt would have problems if they returned empty-handed, and that she would be "their souvenir for homecoming"; so probably they left her there in order to get their own lives spared and returned to capture Eren. Reiner also said that there wouldn't be any hope for her in that place, so there is the possibility that she's dead (but I don't think so).
