Turbotax live used my 2019 AGI instead of my 2020 AGI.  I don't want to be taxed on last year's wages.

 

Are you referring to using 2019 earned income instead of 2020 for EIC and ACTC?  Earned income is not the same as AGI, or as Wages.  

 

The Earned Income Credit for 2020 is computed by comparing two amounts in the IRS's EIC table -- an amount based on earned income – which can be from either 2019 or 2020 -- and an amount based on your 2020 AGI (which includes things like unemployment comp).   Whichever of these two amounts from the table yields the smaller EIC amount will be used.

 

Your 2019 AGI is not considered here.  If your 2020 AGI is too high, it doesn’t matter which year you use for earned income.   Please see Worksheet A -- 2020 EIC -- Line 27 in 2020 Instructions for Forms 1040 and 1040-SR to see how the computation works.  And then please discuss with your TT Live Expert.
