"Upload Coding Data" Feature is not appear

Hi!
I have creator account. But “Upload Coding Data” is not in dashboard. I did star rating in sandbox. But there is not option to upload those data and do rest of analyzing work. After going to "Project set up & access " > selecting my project > Coding data> view specification, it is nothing in upload file. So is there any way to upload coding file and and to do the analyzing work?
Thank you!
