I would first print your
2016 and 2017 state returns and compare them line by line. This will help you
determine what has changed, if there are any discrepancies/items you missed or
if you need to change any of the information you entered into TurboTax.
There are several factors that go in to determining the
taxes you owe.
If your income decreased, that sometimes can reduce your refund
due to you not having enough earned income or withholdings to receive the deductions or credits
you did before.
