That is correct...you report all your income on the NY tax return (the software will transfer it all from the Federal section)…..and NY will calculate their tax assessment on all of it in your case....even the FL income. So if you did not have enough excess NY withholding on any other income you earned during the year, you might end up owing a balance due to NY when you file.
If you had worked 2 months in PA...or CO, or any other income-taxing state, then that other state would have dibs on taxing that 2 months of income. NY forms would still calculate a tax on all your yearly income, but in this case, NY would allow you a NY credit for the taxes you ended up paying the other state. (Of course, in that situation, you would have to prepare the other state's non-resident tax forms first...and pay for the software to file them to that other state, as well as the NY state forms)
If you continue to work in a non-income-taxing state during the summer, and if you have taxes-owed to pay NY every year at tax time, you should strongly consider making regular quarterly estimated tax payments to NY every year to approximate the taxes you will owe to NY on that extra income when you eventually file the tax forms....such that you owe them little, or get a small NY refund at tax time.
