After you file

 A lot happens between the  ACCEPTED FOR PROCESSING  bar on the IRS tool and the APPROVED for refund dispersal bar.  I wish there was a better meter but there isn't at this time ... the code 152 simply means you are between step one and step 2 ... nothing more nothing less  and you must be patient until they finish.   See this road map :  https://www.taxpayeradvocate.irs.gov/get-help/roadmap/
