Similar situation here, refund mailed mid-April, not able to get anything from IRS "Check Refund Status" inquiries. So if you sent in March and have not been processed, guess I should not waist my time checking. Good info from Champ, had found all the same on IRS site. Tempting to resend just to be sure no penalty for not filing by 7/15, but irs says "do not re-send or call" them, so will resist sending again.
