Get
an
accountant
Seriously, esp with taxes that goofy (3 states, ugh). One mistake will cost you way more than a couple hundred to an accountant. And having a continuing relationship with an accountant is worth more than they charge.
Accountants do taxes, all year, they understand taxes, they don't understand your job, why do you think you understand theirs?
Mine was pretty complex last year, 2 states, a rental, a small business, a bunch of investments
it was under $300.
Of course, it all depends on how you keep your records, poor record keeping will cost you.
