If you have already e-filed the return **AND** the return has been accepted by the IRS, then do absolutely nothing at this time. If the IRS needs additional forms they will send you a letter in the U.S. mail to the address you listed on the return, requesting the additional information needed. If/when that happens, make sure you follow the instructions in that letter to *absolute* *perfection* and do no more or no less than the letter instructs. Deviating from the instructions provided by the IRS has a fairly good potential of delaying the processing of your return even longer.
