If that is the only income your child had in 2016 and it less than $1050, it doesn't need to be reported anywhere.
However, if your child had more unearned income than $1050, but less than $10,500, then you have a choice to either report it on your child's tax return or your own tax return. To report it on your own tax return do a Search (top right corner) for "8814". Then click on "Jump to 8814" and enter the information from Form 1099-DIV and 1099-INT.
Limits and other information for tax year 2019 can be found here. [Edited on 04/05/2020 | 10:15 am PST]
