It looks like I can print for mailing, then NETFILE. But not the other way around. I did it for CRA but not for Quebec, and now need to print my Quebec return for mailing (after having filed it by NETFILE) in order to mail Quebec form TP-1012.A-V which must be mailed separately, it cannot filed by NETFILE. Also, when TurboTax usefully told me I need to print and file TP-1012.A-V by mail, it offered to print it, but printed it with watermarks, not useful.
