I used TT a few years ago and filed in mass and florida. It was easy.
I use TaxSlayer.com myself, it's registered with the IRS as a e-filing service, and multiple state filings are easy. You may even qualify for free filing and not be required at all to pay for the service. I've use TT in the past and find TaxSlayer to be much better, check it out and let me know if you need any help with it.

WizeOne - You may want to reread the description - "TaxSlayer.com: Free Federal tax return preparation and e-file if your AGI is $56,000 or less and you are age 25 or younger or 65 or older or you are active Military or if you qualify for the Earned Income Tax Credit or if your AGI is $10,000 or less regardless of age. Includes Form 982 (Mortgage Forgiveness Debt Relief).
Don't know about the various states.
A previous post about filing in Mass and FL brought a small grin. Florida doesn't have an income tax. Instead, there's a simple form for what they call "Intangible Tax," and that is only required for high earners.
