Intuit might have jumped the gun making that app available when it was too late to get that 2019 non filer info into the system. IRS had already locked in the 2018 info for the EIP.

IRS never let the software providers know they would be using 2018 info if the 2019 info hadnt been received before the end of March...which is what appears to be happening to many people.

There is nothing Intuit can do to "fix" any of this.
