Username and password combination isn’t right

hey, first time using Infuse 6, I opened a new “Sharing Only” user on my Mac, and on the “File Sharing” option I chose the wanted folder and on the Users tab enabled the “Sharing Only” user I made with a “Read Only” option. on the “Options” tab I enabled “Share files and folders using SMB” and “Windows File Sharing” and chose the “Sharing Only” user. now on my Apple TV 4K I type in the username and password and every time it says its not correct
