After you file

This is my theory again just what I take from studying up on this crap for days waiting for my money!!

 

When you use TT they send your money to SBTPG who takes our their fees or to pay back the advance, SBPTG makes an accounting/routing number to get the fees. Once completed they send your funds to your card using TT accounting/routing numbers. 
SBTPG has now closed those accounts since you have already paid the fees.

 

The IRS only has accounting/routing numbers for closed accounts from SBTPG so therefore the stimulus checks will be rerouted and you will be sent a paper check.
