Would I subtract one from the other to know amount I'm still accepted to receive or is second amount the total overpayment? Thank you again

First, the changes on an amended tax return typically assume that any previous refund amount has been received. However, this should be checked by downloading the PDF by following these steps:

1. From the left menu, select Tax Home. 
2. Scroll down to Your tax returns & documents and Show.
3. Navigate to the option to download the PDF of your return.
   • The forms are named in the top left and lower right hand corners of each page.

Navigate to Form 1040-X, Line 18, which is: Overpayment, if any, as shown on original return or as previously adjusted by the IRS.

Second, the IRS does not want taxpayers to amend their tax returns if the changes are related to tax law changes from the American Rescue Plan. The IRS will automatically recalculate these adjustments in many cases.
