Ebay invoice

I recently sold something on ebay with the assumption that there was a selling fee for ebay included in the transaction, but now I have an email invoice asking me to pay ebay immediately and am not sure if this is an official ebay email or if it's a scam. I'm not getting any corresponding notifications on my ebay app or the website, so am confused and wondering if I need to take any action?

As you are not on managed payments, your ebay final value fees are billed monthly.  You would owe

approx  $15.15

Note any additional paypal fees would have been deducted from your payment by paypal at the time of transaction.

Don't click in the email.

Instead, log into eBay and select account then seller account.

There you can see if there are any fees owing.
