Why we are saying it as carbaminohemoglobin not carboxyhemoglobin???​

that carboxyhemoglobin is (protein) the stable complex of carbon monoxide with hemoglobin; it prevents the normal complexing with oxygen and thus leads to anoxia while carbaminohemoglobin is a compound of haemoglobin and carbon dioxide, one of the forms in which carbon dioxide exists in the blood.

Well, this is what I know from school but if you have any questions about this feel free to ask!!

Hope this helps and best of luck to all.
