Deductions & credits

It isn't moot.  Turbotax assumes the amount was mailed or deposited simply because the IRS letter says a credit for the amount was "issued," and then Turbotax perfunctorily zeros out the $2800 which should be a credit to us.  I had to lie in Turbotax and say the amount in the IRS letter was the wrong amount.  I shouldn't have to lie to get the right amount placed in the right spot on my return.

If IRS had mailed us a check, they would have clearly stated that on their ARRA inquiry website.  They never claimed to have either mailed or deposited the amount.
