@NCperson Yes, that is correct! I had entered a lower amount and was unaware that the IRS would automatically do the changes and no amendment was needed. I filed my taxes in Jan and was advised by a TurboTax rep to complete 1040 as it had been over 21 days and I still didn't receive my taxes. It wasn't till Friday when I called that the person whom I spoke with advised me that there was no need for me to file 1040 she even indicated that she would never recommend using TurboTax as a lot of errors can be avoided but TurboTax is advising their customers to file 1040 which is only making the process longer.
