State tax filing

I've updated the return.

 

I am still getting one issue on form IT-112-R (CA):

 

24 Enter the amount of income tax imposed on this year's return for the other state or local government that was paid by the:

24 a Taxpayer 0

24 b Entity on behalf of the taxpayer 13,587.

 

What number do I put for 24 a? I thought that 0 is correct because I didn't make any estimated tax payments. But this number isn't accepted.
