Adding a State return

I have completed my Federal and State Tax returns, but forgot about income that came from the sale of a property in another state. Should I add the new state income to the Federal section first? or download that State's program and add it there first.

Thanks for any wisdom here.

You will need to amend your returns first, then complete a nonresident state return. Wait until the original returns are fully processed before amending to avoid errors.

How to amend a return you have already filed?
