AdSense Account Validation Issue: Need Help Identifying Account

Hello DigitalPoint Community,

I hope you're all doing well. I'm facing a bit of a challenge with my Google AdSense account, and I'm reaching out here in the hope that someone might be able to offer some guidance.

Here's my situation: I have a website, https://www.trtdigital.ma, where I run Google Ads. The website is fairly established, and I've been using AdSense for a while. However, I've recently encountered an account validation issue.

Google has informed me that my AdSense account is not validated due to having another account. The thing is, I do recall having another AdSense account a while back, but that account was canceled, and I thought it was all sorted out.

Now, I want to get my current AdSense account validated, but I'm stuck because I'm not sure which AdSense account is associated with the page https://www.trtdigital.ma/2020/07/18/top-10-service-livraison-e-commerce-au-maroc/. Is there a way to identify the AdSense account being used on this specific page?

I've tried reaching out to Google's support, but it's been a bit of a challenge getting a clear response, which is why I'm turning to this community for some insights.
