2022 Tax return has not received even after reporting using TurboTax

[minjeong an]

I purchased your service and my husband was supposed to receive tax return.

However, even in the end of July, CRA said "our 2022 return has not been received."

I was wondering if the submission was conducted successfully.

Also, I attempted to call CRA, and they are not receiving the call for 2h, probably due to higher volume.

I did not set up NETFILE, so I do not have a way of tracking those files. 

What is the workaround to handle this situation? Is there a way to submit the form to CRA in the mail?
