Both State 1099G & amount that pulled into software this year for state refund is $1319.Last yr state filing & actual refund received was $1064. Why don't they agree?

On this year's (2018) federal return, the amount that is showing up in the software for last year's state income tax refund is $1,319.  I checked with my state's website and it also shows $1,319 on the 1099-G.  However, my filing with the state last year through TurboTax had a refund of $1,064 and I confirmed that we actually received that amount in our bank account. Can you tell me why they do not agree?  Thank You  Michael Sullivan
