Sorry--you cannot do that at this time. When you prepare your 2020 tax return, IF the child qualifies as your dependent for tax year 2020 (and we cannot be sure of that without more details) you will get the stimulus money with your 2020 tax return. Right now the IRS is using information from returns filed in 2018 and 2019 for stimulus money. If you "just" got custody in 2020, you cannot get stimulus money for that child now, nor do parents of babies born in 2020 get stimulus money for those babies in 2020. Wait for your next tax return.
