I filed sometime in early March, they sent it around March 10. Return was accepted within a couple days (basically immediate business-days-wise, I think I filed over the weekend). All pretty quick. But no letters to explain anything, and no responses to my contact attempts.

My state sent me a tax refund of less than I was supposed to get. I have no idea if this was a clerical error, but they never sent me a letter explaining any adjustments on why I would be receiving a lesser amount. As a practical matter, is it better to deposit the check and fight them for the remainder or have them void the check and send a replacement for the correct amount? Of course all assuming they ever respond to my contacts on why they're underpaying me...

The other unusual thing is they sent it via check even though I selected DD (and federal + the other state I lived in part of the year sent it via DD). Perhaps more room for clerical error.
