I'm having a similar issue but I'm wondering if it's a technical glitch. I initially used my 2020 numbers to calculate EIC. When I revisited the section to try my 2019 income number (which is lower) It makes no change in the calculation. I thought it was odd that the credit is identical with different income numbers. Even after changing to the 2019 option, Turbotax displays the 2020 figures under the "explain why" information. I'm also curious as to why my last year's credit shows a much larger number (in TurboTax) if I'm using the same information to calculate this years'. I tried putting the figures into the irs.gov "Earned Income Tax Credit Assistant" and got the matching number for 2020's info but a much higher number with my 2019 income. Anyone have a good explanation for this?
