How can I tell if my taxes have been filed

If you receive a NETFILE confirmation number, your income tax return has been successfully transmitted to the Canada Revenue Agency.

I completed my tax form, followed by my husbands (they were completed together)  I did receive notice that mine was received, however I cannot see that my husbands was sent.    Question: do they get sent together online at one time?  I filed right when CRA locked thousand of accts, I've been 'revoked' since.  Have been calling CRA to no avail.
