It gives me an option to use my 2019 income for the eitc this year, but i already filed last year using them... I says I can use my 2019 income if it was greater???

[kennynemet]

does this have to do with the cares act and tax changes or should i just decline using my 2019 income??? Because I ALREADY FILED WITH THAT INCOME last year...

Yes, The lookback rule is part of the Coronavirus tax relief package.

The special lookback rule will allow lower income individuals to use their earned income from 2019 to determine their Earned Income Tax Credit and the refundable portion of the Child Tax Credit in 2020, since their lower 2020 income could reduce the amount they are eligible for.

You can look back and use your 2019 income for the EIC credit instead of 2020.  See this post  https://ttlc.intuit.com/community/taxes/discussion/i-m-at-a-section-asking-me-do-you-want-to-use-las...
