Shania, last year was my first tax return while living in the UK. I had to fill out a state tax return last year as I had worked in NY for part of that year, before I moved here and got some money back, to boot. Helen explained that this year I would only have to fill out a 1040 and 'break residency' with NY. I assume it would be the same for you but ask Helen.
TurboTax is software that prepares your taxes for you, all you have to do is answer a series of questions about your income, taxes paid, expenses, etc. You can do it on line. It costs $19.99 for the Federal return. I would have been lost without it last year. Their website is TurboTax.com
