Yes. The software is overly optimistic, but it's probably a result of some settings you haven't adjusted.
Depending on the software you're using there are a LOT of variables to adjust.
But you won't know for sure until you brew it. Efficiency will depend on your system and I wouldn't rely on the numbers from the software until you've dialed in your process.
Not that you asked, but if I were converting that recipe to partial mash I'd add several pounds of 2-row or pale malt, decrease the amount of extract to balance the expected OG, use light instead of amber extract, and increase the caramel/crystal and cara red to get the same SRM.
If you're going to go for a partial mash, use as much base grain as possible, IMO.
