Adding SSH Key issue

I was recently adding an ssh key using

echo -e “neval $(ssh-agent -s)nssh-add ~/.ssh/id_rsa” >> ~/.bashrc

however I mistyped and theres no space after add~/.ssh

The issue I have now is that when I open the command line instead of it opening up and resquesting my password I get the following error

Agent pid 204951
-bash: ssh-add~/.ssh/id_rsa: No such file or directory

I cant seem to remove this so I can start again,
Entering ssh-add ~/.ssh/id_rsa only works to get an initial connection but nothing long term
