All you can do now is, wait. At least you know that MD has your filing. It does not matter who sent your form to the Comptroller's Office of Maryland . That is the sole destination for MD state tax returns. No one has discovered a way to make a tax agency speed up sending out refunds. No one ever will because they are an overwhelmed, over worked, under funded and under staffed government bureaucracy. Eventually you will get the pay off of your no interest loan to the government.
Have you thought of paying just enough by estimates or withholding to avoid a penalty and let the government wait for your check?
