Hi Sereng,

❝ […] I believe you are stating n=750 per group in this parallel group study (total n=1500) using the assumptions from the completed study? Correct?

Nope. Pasted from my previous post:

Sample size (total)
 n     power
750   0.800246

The sample size functions of PowerTOST give always the total sample. If you are interested in the background, see this article.
