Hi my name is ***** ***** I have been in the plumbing field for 20 years. I will be glad to help you today. Are you able to get the screw out but not the sleeve or not able to remove the screw also?
To remove the screw try taking a flat head screwdriver and wedge it into the edge between the sleeve and hole and that will hold the sleeve while turning the screw with another screwdriver.
If you have replacement sleeves and screws then once you have the screws out you can either pull the sleeve out with some pliers and if it is too hard to pull out then just push it down through the hole and it will drop down into the hollow area under the toilet. There is a small hole there and you may be able to get the sleeve out of the hole after it drops inside but no big deal if it just stays there. It will not hurt anything to leave it there.
