Arguments for taxonomy_featured_image?

For some reason my taxonomy featured image is being displayed at medium size (that is, the actual medium image is being pulled in). I suspect a conflict and will have to do some troubleshooting (the theme is a hot mess with at least a dozen JavaScript files, and there are a lot of other plugins), but wondered whether there are any arguments you can use for taxonomy_featured_image or taxonomy_cover_image to specify the image size.

Thanks!
