Topic 152 is a generic topic code that means your return is still being procssed. Once the IRS finishes your return your status will be updated on where's my refund.

Nothing. It can happen while the return is being processed. It will come back when the processing is complete.
So if there is no status bar for my return and it says “your return is still processing a return date will be posted when available” and I have no topic code what does that mean?
Until the IRS accepts or rejects your return, they won't have any record of it. Once you've been accepted, wait at least 24 hours before you use the IRS Where's My Refund? site. If you jump the gun, you may be told?—incorrectly?—that you never filed.
