Chiwill ,
You were able to check the status of a TurboTax submitted non-filers registration at the IRS's non-filers portal?
When I go to check my status at that portal it says there is no filing under my SSN. When I try to register at that portal is says there is already a filing under my SSN. (!!!!)
So, I interpret that to mean the IRS's portal can only be used to check registrations submitted through that portal.
(I had no income in 2019.)
