You will have to request the set to be added. To start, make a spreadsheet or a text file with 2 columns
Number - Name
Then you make the checklist, you can use the site linked as a sample. Each card name should be the character(s) name from the front of the card. Although some might say you should use the first line of the paragraph on the back (the FAQ doesn't specify how to name cards like this.)

Then go to the Year page of the category (1999 of Non-Sport)
https://www.tcdb.com/ViewAll.cfm/sp/Non-Sport/year/1999
There is a green Add Set button on there to click. Then you fill out the form. In additional info, you put in "cards do not have names or titles on front or back. Released in Italy." Then under that paste the checklist you made. It will go in as an IR and someone will take it over and if they have questions, they will ask or you'll get a notification when the checklist is added.
