Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.

Americans pronounce confused as kuhn-FYOOZD (/kənˈfjuzd/). Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "He explained the offside rule to his friend who was confused".
Record yourself saying "confused" and play it back. The mic stays on your device — nothing's uploaded.

Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.

Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
Touch the tip or front edge of your tongue to the roof of your mouth behind your teeth. Air flows through your nose.

Lift your bottom lip to touch the very bottom of your top front teeth. Blow air through this contact point without voicing.

Start with the tongue mid-front raised high, almost touching the roof of the mouth (but not touching). Glide into a tight lip circle as the tongue back lifts.
Same position as S, but add vocal cord vibration. Feel the buzz.

Touch the tip of your tongue to the roof of your mouth just behind your teeth. Add vocal cord vibration as you release.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "confused", the "d" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
Stress falls on the second syllable, not the others. Stretch FYOOZD — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
