Does anyone know why I cannot access my 2020 return on TurboTax after filing for the extension? I found more documents to enter and could be the reason i was rejected.

I kept getting rejected time and time again due to EIC and I filled out the forms needed, but was still rejected. So I filed for an extension so I can still submit it while I researched the issue. I found a few documents after a couple of months that I don't think I entered and wanted to see if that will fix the issue. But when I returned to turbotax, it says my e file was accepted but when I went to track my refund, they don't have any records of me filing. Can someone help me?
