Amending a return

I am in the process of amending my 2022 tax return.  I entered a lower dividend number on the amended federal return as a result of receiving a corrected 1099.  This resulted in a federal refund since I paid more federal tax than I should have.  However, my state numbers did not change.  Why doesn't the lower dividend number on the federal return flow through to my state return with a resulting state refund as well?
