@Banless Again----it has nothing whatsoever do to do now with your 2019 return. There is nothing you need to do now in regard to your 2019 return. Changing it will not have any effect on getting stimulus money for your child now.
The recovery rebate credit is based ONLY on what you file for 2020. If you had prepared the 2020 return correctly and claimed your child, you should have seen an amount on line 30 of your tax return. Was anything on that line?
If you prepared a 2020 return and did not use the recovery rebate credit to get the 1st or 2nd stimulus amount for your child on that tax return, then after it has been fully processed you can send in an amended 2020 tax return on a Form 1040X. Do not expect quick results----it takes the IRS at least six months to process an amended tax return.
