Skyrim lost in the past?

I started the quest lost in the past and almost finished it. I'm already in the etherium forge, have defeated all enemies and now the ghost katria told me to forge something as proof, but I did that too, but even if I did what has forged is not completed the quest I'm still being informed that I should forge that is a problem because the only entry and exit of the forge only opens when you have completed the quest have reloaded several times and each time something different forged but it still doesn't work. I play on the xbox if that helps

"I play on the xbox if that helps"

No, unfortunately the opposite is the case. You can fix almost any bug on the PC, but you are very limited on the console.

Don't you have to talk to Katrin as soon as you've forged one of the three items? If you really have no way of completing the quest and getting out, you will have to load an older save. Then you can try again and hope it works this time.

Yes, I've already tried it so I'll probably skip the quest
