TurboTax based my EIC n 2020 off my 2019 taxes, but the IRS redid them using 2020s,lowering my refund alot.For 2021 do I Use 2019s "lookback" or just use 2021s lower EIC?

IRS refunded me in 2021 using the numbers from 2020, not 2019 lookback method like I had checked off to do. I'm so confused and don't want to waste money preparing taxes again, only for them to be redone and sent a much smaller refund. Any advice/suggestions or similar experiences? I'm not sure what to do to avoid delays even though the lookback method (using 2019 tax

You can try using the 2019 earned income amount but the IRS did not like the amount you used before so make sure you use the correct earned income from the 2019 return ... otherwise don't risk it.
