Incorrectly received Groceries and Essentials Benefit and BC Climate Action Tax Credit fromCRA

We just had $800 deposited into our account from the CRA. My partner checked their CRA account, and the letter said it's for the Groceries and Essentials Benefit and the BC Climate Action Tax Credit.

However, as far as I can tell, these are for low income individuals.

My partner makes about $180,000 a year, and I make $80,000, so we shouldn't qualify.

Any ideas what happened, or what we should do?
