They cashed the check, but since it was lacking the 1040, they assumed it was a estimated tax payment for 2010, not 2009. Now i have a credit on for my 2010 year, but 2009 is on limbo. I have to refile again, hence i am hoping by doing so in person and with a IRS received stamp it would be enough. This is the only thing holding up loan docs and its so frustrating. I assumed my 2009 taxes went thru because the check was cashed.
