Update for in case others run into the problem in the future here's what i did
Ok so i did it today and it linked on my second try heres what I did.
first ensure you only used the information for the principle applicant not the sponsor information
second choose application number and last name then type in the application number and the last name for the principle applicant
third choose passport over birth city I orginally was only using birth city but it wasen't doing but this time i used passport for the first time
and after doing all of that it worked oh and don't forget to choose 2 instead of 1 if its just for one person thats also important
