For the record, my stimulus just showed up on my Bluebird (American Express) prepaid card, which I used for my 2018 return. (I didn't finish my 2019 return till a week ago Sunday; my refund was approved Friday with a DDD of 4/15 but hasn't hit my Varo account yet.) Though I didn't use SBTPG either year (I always use the IRS Free File version of TurboTax so I don't have any fees or advances to repay), that at least proves stimulus money is going to prepaid cards the same as to regular bank accounts. (Edit: And if you were tardy filing for 2019 like I was, try looking where your 2018 refund went to.)
