@mikemelaniehall - absolute worst case is that you'll have the opportunity to correct it on your 2020 tax return next year. the IRS used the 2018/ 2019 income and dependents to create an ESTIMATE of how much stimulus you are due, The 2020 tax return will be used to calculate what you are ACTUALLY due. it'll work out.
certainly if your 2019 tax return is incorrect because you didn't get the correct tax credit for the child, amend!!! the stimulus money will eventually follow
