I have 2 profiles by accident

See the help page that explains how to merge names - https://help.imdb.com/article/contribution/names-biographical-data/how-can-i-combine-two-imdb-name-pages/G3TNPWSGKZNRU3MP?ref_=helpsect_contrib_2_6# If all the information on both pages is yours then merge is the right thing to do. If you have a problem following the instructions on the help page, post back here saying what you did and what happened and staff or an experienced contributor will be able to help you.
