What happens if an individual accidentally says Aneinu before Re'eh instead of during Shema Koleinu?

Question

Let’s say that a congregant, who’s normally supposed to say Aneinu in Shema Koleinu instead of before Re'eh, accidentally says it as a stand-alone Beracha before Re'eh. He doesn’t realize until well after 3-4 seconds.

1. Does he have to say Aneinu again during Shema Koleinu?
2. Does it count as a Beracha said in vain?

Answer 1

The Kaf HaChaim writes here that you fulfilled your obligation if you accidentally says it as a stand-alone Beracha before Re'eh. Therefore:

1 - You do not say it again in Shema Koleinu.

2 - It was not a Beracha in vain.
