Same boat as you. I just found out that if you file jointly the child tax credit has a cut off of $110k income. So for me I didn't receive both child tax credits in 2019 because we too are above the $110k. The stimulus check threshold is maxed out at $150k so when they looked at last tax return I only had 1 child credit & therefore only received 1 child as part of the stimulus check.
I think they'll catch on and provide some kind of form to fill out if you received the incorrect amount.
