Your wife was born in 1956, so she is 63 at the end of 2019 and is still eligible for the Earned Income tax credit (EITC) as she is younger than 65. In TurboTax, you just enter all information and income and TurboTax will automatically calculate the amount of EITC you are entitled to.
 

Please read this TurboTax article for more information.

If you think you qualify, and TT missed it, In TurboTax (TT), enter at:
