Earned Income Tax Credit EITC

Already filed 2020 Taxes for my 17yr old Granddaughter.  This is the first year she has filed on her own, not as a dependent.  She had a AGI of under $17K, not married and no kids.  TurboTax for Feds indicated she didn't qualify for EITC.  However, TurboTax for the state of California indicates she qualified for EITC, not much but something.   I've answered EITC questions both ways...she did receive a letter of disallowance from both Fed and State and ...she has never received a letter of disallowance from both Fed and State (that I'm aware of), which is actually how I answered the questions in TurboTax before filing.   In both cases, TurboTax indicates she qualifies for EITC.  Recently checking the State site for EITC Calculator the site indicates she doesn't qualify, which makes sense; especially for her age.  Just received a letter from the CA. FTB disallowing some of her Tax Refund, that was initially indicated by TurboTax, for her NOT qualifying for EITC.  Tried to go back in to TurboTax and see what went wrong but I cannot get TurboTax to NOT qualify her for EITC???  One other thing.  The "Explanation of Changes" from the State states "We disallowed your Earned Income Tax Credit because you or your spouse/RDP exceed the age limit.
