You need to use Cinema Tools, which is a database of all your quicktimes, with timecode, reel and keycode information, and this database is linked to each individual quicktime that you edited with.
You can then produce your lists through this combined information (within Final Cut, File menu, export, Cinema Tools film lists) . If you don’t have a cinema tools database, you can export all your clip information from the FCP brower as a final cut pro batch list, and import that into cinema tools, add all the keycode information, and link all the quicktime files.
Usually the telecine facility provides a flex file, which has all this information, and is imported into Cinema Tools to create the database. Then this database info is exported as a final cut pro batch list, imported into FCP, and used to batch capture. Then the captured files are linked to the database records, and the information is linked both ways.
Since you’re near the end of the process, you can still accomplish lists, but you’ll have to build the info from Final Cut backwards.
This is a dated article, but it gives the basics:
