"I registered"

That log in from TurboTax, and here, would be the same. You didn't need to Register, here. And that's the problem; you are not using the Programs, here. No one here is using TurboTax. These are all different tax prep programs.

"so I wanted to try my luck here first."

But your tax dollars already support the IRS. Go There, First.

"and for 2019 year only $80,000." <== meaningless

"I did NOT get my 1st Stimulus Check, but I got a $1,200 check for the 2nd Stimulus." Only needed for reconciliation, which means "what do I qualify for?" and "how much did I already get?"

Perhaps it would help to review what is really happening:

The funds were paid out as Advanced payment against a projection. The projection used 2018 or 2019 tax returns. But 2020 is the Actuals. You use the 2020 return to reconcile what a person is entitled to, against what they got.

If the person is not a dependent in 2020, then they would be entitled to the payment/credit. That doesn't mean "not being claimed." It means "no longer qualifies as a dependent."
