I have opened a few of my clients after their returns were filed wherein the software suggests an Amended return might be necessary to file because the taxpayer was not entitled to receive the unpaid amount claimed for the economic stimulus payments.  In at least one case the client absolutely did not receive any stimulus payments yet the tax software indicated the taxpayer was not entitled to any stimulus payments.  I directed him to open an individual taxpayer Account on the IRS site and seek a way to file a claim there.  How reliable are these suggestions from the software?  What remedy might there be?  I have alerted at least a couple other clients that they may not get the missing stimulus payments even though they appear to be eligible.  Does anyone have similar experiences?
