I am sorry, but it takes approximately 8 to 12 weeks for the IRS to process an amended return.  You  will have to wait until your amended return has been processed in order to be eligible to receive the stimulus payment on your additional dependent.  

After this time, please contact the IRS at 1-800-829-1040 between the hours of 7 a.m. and 7 p.m.
