HRB's tweets mention Green Dot bank. Turbotax's banking partner is SBTPG, and SBTPG has released a statement that they are returning all direct deposits to closed refund transfer accounts to the IRS.

I don't have an authoritative reason for this, but I can guess that because Turbotax's market share is much higher, there would be many more customers affected making the work needed by SBTPG that much harder. Also, SBTPG is actually following the law and IRS regulations, and Green Dot (if they are re-opening closed temporary accounts to process payments, without a signature from the customer) is violating several banking laws. (Remember when Wells Fargo was caught opening accounts without authorization to generate extra fees? That's illegal now.)
