I think I've accidentally filed two 2022 refunds. How can I delete one of them if two have been filed? Or who should I contact

Did you get NETFILE confirmation numbers for both of them?

It looks like just 1, but its the one I was trying to replace/update. Im not sure how to cancel the first

You can wait until you get the Notice Of Assessment, then use REFILE to fix the return you sent, or you can try contacting the CRA and see if they can cancel the return. 

If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
