Thanks for the reply. I can confirm that last year I itemized deductions and used my state income tax, not state sales tax in itemization. But I still don't understand why my 1099-G would be different than the amount I received.
I'm wondering if there is a portion of my refund that is not subject to federal income tax to account for this difference. For example, Colorado has a TABOR refund that, based on my Googling, looks like it wouldn't be taxed by the IRS but would have been part of the money received in my state refund last year. However, if I subtract this amount from what I received from the state last year, the result is less than what I see on my 1099-G, so I'm still uncertain and confused.
