After you file

The IRS has my 93 year old moms direct deposit for about 15 years and  gets her Social Security by direct deposit every month for the past 20 + years.!!!  Now when I log in to the Governments "Get my Payment tool", which I have done for the past 2 weeks for my mom using her same info, Name, Social Security #, Address that she has has for years,  I IRS says her information is not valid even tho on the third of this month she had a direct deposit into her bank from Social Security.!!!  Now how can this be possible.  Do the IRS have Brains.???  Please explain.!
