Reason for amending state return

I realized that some dividends should have been indicated as coming from US government sources and would be non-taxable at the state level. I have to now amend my state return, and it asks if the reason for amending state is because of a change in the federal return. My federal return has not changed (and I would not file an amended federal return), but the 1099-DIV  change from US government sources goes in the federal portion of Turbotax. Does this mean that the reason for amending the state is due to a change in the federal return? Thank you!
