This is what Turbo Tax said:
How does the new law affect my Earned Income Tax Credit?
There is a special temporary rule allowing individuals to use their earned income from tax year 2019 to determine their eligibility and amount of Earned Income Tax Credit and the refundable portion of the Child Tax Credit (i.e., the Additional Child Tax Credit) in the 2020 tax year. TurboTax will help you to do this when you file your 2020 tax return this year.
but I can't figure out how to do it!!!
