Made an error on date of birth of spouse and rejected by cra. I was successfully filed mine. Is there a way to refile without us paying another 79.99

Usually when there is a mistake like that- they end up rejecting your return and not allowing it to go through NetFile. Please try going back to spouses return- FILE and go to NETFILE to see if it will allow you to click on NETFILE once again- after you update her date of birth.

but when I fixed his date of birth, the system is asking me to pay again the spousal package of $79.99

Then try to ReFile with the appropriate date of birth.
