Yes, you can use your 2019 earned income instead of your 2020 income to compute the Earned Income Tax Credit and the Child Tax Credit if your 2019 earned income was more than your 2020 earned income.
Please wait until your original return has been processed before filing an amended return (Form-X). You can e-file your 2020 amended federal tax return, but most states require amendments to be printed and filed by mail. Please see FAQ How to amend a tax return for instructions.
