Trying to Amend my 2020 return but not getting charged the automated amount the system is requesting back that it thinks i recieved??!!?

hello i am currently amending taxes for 2020 taxes to be accepted by the irs, however the system assumes that i have gotten the previous amount on my original taxes. Which I have not. There was a couple of questions and answers in a similar forum, adressing this kind of situation. One answer , explained that an amended return shouldnt be followed through with on the system if the original was not finished processing, for the sake that the system requests the money back from (me) or said taxpayer of the difference in the amendment. However, the irs representative said that the amend needs to happen first as they will not be finalizing the first return and remain keeping the refund on hold until the refund is amended...what should I do in this regard? Is this something anyone knows a specific answer, with turbo tax's automated adjustment?

Thank You!
