Don't worry if the monitor goes to zero when amending your return -- this is not unusual.
Basically you are "amending" your return without changing any of the original amounts, since you did include the Recovery Rebate. It sounds like the IRS suggested you file an amended return without changing anything, except including an explanation of what has happened.

The IRS, tax preparers and tax software will not have additional information on refund dates, so the IRS tool, Where’s My Refund? remains the best way to check the status of your refund. Where’s My Refund? is only updated once daily, usually overnight, so you don’t need to check the status more often.
