Welcome to FT!
I think the checks you are talking about depend on the credit card issuer, which would be Chase for United. While I don't have a UA card from United, I know that any convenience checks from my Chase Marriott Rewards Visa not only do not earn miles but will also post to the account as a cash advance. Not sure about the specifics though.
