I printed and emailed my tax return, but I still haven’t received any notifications. I sent all the documents by mail at the end of March, but I can’t see the status.

I printed and emailed my tax return, but I still haven’t received any notifications. I sent all the documents by mail at the end of March, but I can’t see the status of my tax return, especially since I don’t have a CRA account and haven’t been able to create one.
