irs not allowing economic impact rebate recovery on filed returns

Did the actual return change?  or are you just seeing the bug thats been happening since the 11th?

"We put in for the other 368"

832 + 368 = 1200

That's only the First payment.

This person would also be entitled to the Second payment, the $600.

Perhaps it would help to review what is really happening for EIP “stimulus” funds: The funds were paid out as Advanced payment against a projection. The first two payouts were projected based on 2018 or 2019 tax returns, but the eligibility is part of tax year 2020 as 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 eligible for consideration as individual filers. That doesn't mean "not being claimed." It means "no longer qualifies as a dependent." You must correctly address whether they Can be Claimed as a dependent on someone else’s tax return.

The third payout which started in Jan 2021, has different eligibility rules as to dependents and this payout is a projection, using 2019 or 2020 tax returns, then reconciled against Actuals on the 2021 tax return.

One for each of the three EIP “stimulus” payments.

IRS does not change returns in ProSeries.  IT IS NOT POSSIBLE.   If IRS is going to make a change to a return the taxpayer receives a letter.    The change you are seeing is a program issue.
