TNT Dome 7 Hunt – The Rose Room.

Howdy, I'm currently on a quest to get every TNT dome and I've managed to get 2&3 but now I'm on the trail of number 7 and I've done nearly everything up until the guide mentions Ingraham Mansion.

The guide I'm using is outdated since as I arrived to the mansion I've learned it's become The Rose Room. Is it still possible for me find the terminal with the one time pass code or has it been moved elsewhere?
