I’m also in the same predicament. Filed jointly with my wife for the first time in January. Had our first born late 2020. No issues with the first two stimulus checks, or taxes. All the sudden $2100 shows up. It’s more than for one person, not enough for two. It’s still in “pending transactions”, so I was going to wait to start getting on the phone (because that will be a pain) until it clears. I’ve been typing different things into the search and this is the only thing I’ve seen so far.
