Where Is My Refund?

Dear IRS,

I, a taxpayer, am owed a refund from your organization. I'll admit is isn't a very large refund in the grand scheme of things, but $300 or so isn't pocket change either. The TurboTax software says it you accepted my tax returns when I electronically transmitted them over 3 weeks ago. One reason I use TurboTax is because I get my refunds quicker that way. In years past you managed to get the refunds to me quickly. What is the hold up?

Please give me my refund soon.

Thanks,
Concerned Taxpayer.
