Americans pronounce generally as JEH-ner-uh-lee (/ˈdʒɛnərəli/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The weather in September is generally pleasant".
Record yourself saying "generally" and play it back. The mic stays on your device — nothing's uploaded.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch JEH — keep everything else short and quick.
Don't pronounce the second syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
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.
