Business & farm

You don't use 2019 income amounts to file a 2020 return ... you must use the 2020 income.   

NOW when you get to the EIC section, if you are eligible,   then you will be given the chance to use the 2019 earned income figure instead of the 2020 figure to see if the EIC credit is higher.   Read those screens carefully ... if it is not helpful then back up and say no this time.
