My refund was way short as well. I got on the website for the IRS and chose the option to check my refund. The IRS is the one that amended my tax return and proceeded to give me multiple details as to why this was the case. 5-6 options were given that it could be, but still not the exact reason why. So now I am sitting on hold with the IRS for 30 mins so I can straighten this out. And getting through to a rep was horrible. I wish you luck!
