Scribe -help
If you just made a fancy chair then it is in the assembly device.
like Khisanth said, check out the assembly device, as scripe you build a blueprint that need assembling and then the item is directly delivered to the guild storage.
At the moment there is no way to stop it from being put into guild storage and I don’t think there ever will be, so make sure you are in the right guild hall when building stuff
