Do you not file a return normally ? Is this for the stimulus check ?
If so there are no details on how this can be done at this time to get a direct deposit ... if you use any of the tax programs right now and don't have a refund you cannot put in the DD info so it is a waste of time.
AARP said that SS & VA benefits recipients do not need to file ... more info to come ... watch these sites :
