For example, I lived in the past in Arizona, so when I do my taxes I print 2 copies, and send one copy to the IRS (the Feds) and the second copy to the local IRS (the Arizona IRS, which is called Arizona Department of Revenue, if I remember correctly)Since I moved to Florida last year, my understanding I dont have to send anything to the Florida IRS (if there is an institution like that), I should only send a copy to the IRS (the Feds), correct?

Typically 3 and 3.
