Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Americans pronounce software as SAHFT-wair (/ˈsɔftˌwɛr/). In "software", the "t" is squeezed between other consonants and drops out — the surrounding consonants flow together without it — most natural in flowing, casual speech; in careful or formal speech, the T may be lightly present. This is called the Silent T in Clusters, and it's why Americans sound more relaxed than the textbook. It comes out as SAHFT·WAIR. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "Beware of the software on the hardware" or "The software has a few different features" — more examples below.
Record yourself saying "software" and play it back. The mic stays on your device — nothing's uploaded.

Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Relax your lips and drop your jaw significantly. The tongue tip lightly touches behind the bottom front teeth and the back part of the tongue presses down a little to create more dark space in the back of the mouth.

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

The T is skipped entirely. Your tongue doesn't make contact at the T position.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "software", the "t" is squeezed between other consonants and drops out — the surrounding consonants flow together without it — most natural in flowing, casual speech; in careful or formal speech, the T may be lightly present. /t/ is dropped entirely — the surrounding consonants flow together without the T.
Stress falls on the first syllable, not the others. Stretch SAHFT — keep everything else short and quick.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
