Thank you for your answer.

I modified my question, I meant to say she has a direct deposit account. In any event, I didn't have a notice of assessment for her. I assume that Quebec will only send one once I file my taxes via mail, correct?

If you send your tax return by mail, then you don't send via Netfile, you cannot file twice one tax return.  If you have sent your Federal return already via Netfile, then you can either Netfile your provincial return or mail it in, you cannot do both.

I did both taxes online for myself. As for my wife, I sent the federal one for her and tried the provincial one for her, but it didn't work (it doesn't allow me to - it literally says it's in the process, or will attempt to, but I then get the error message and cannot continue forward). Which is why I will send it by mail.

Perfect. Have a nice evening.
