California Military Retired Exclusion pay

[MaryY1]

Turbotax is showing my Military retired exclusion pay as $20,000.  But I didn't earn that much.  However it doesn't let me change the $20,000 amount.  How can I correct that or is the exclusion $20K even if you earned less than that.

You are able to correct the California Military Retired Pension Exclusion in TurboTax, in the California state income tax return.

At the screen Any Pension or Annuity Adjustments?, it states:

If your pension or annuity distribution has a California taxable amount that is less than your federal taxable amount, enter the difference as a Subtraction.
