But it kind-of depends on what you mean too.
For most states, the state starts with the Federal income amount, and since most Interest, dividends, and capital gains are already a part of the Federal gross income, there is nothing separate to enter in the sate form.
....except, as noted by @LeticiaF1 , certain special designated amounts that will be either added, or subtracted from the state income forms before calculating the state tax.
For instance, for states with an income tax:
1) sub amounts of dividends (or interest) that came from US bonds is included in Federal gross income, but those amounts are subtracted form state income....as the states don't tax dividend/interest from US Bonds.
2) Sub amounts of tax-exempt interest from various states Muni bonds, those $$ have already been subtracted from the Federal Gross income, but the $$ that came from state bonds issued by states other than your own, are taxed by your state, and those $$ get added back as an addition to your state's income.
Then there are subtle differences to those additions and subtractions, primarily related to tax-exempt $$ in #2, if you live in UT, CA, MN or IL
