Since you can download prior year tax files and the issue is only with the 2020 download you will need to connect with TurboTax support again. Give them your prior Incident number and make sure they understand the problem is not fixed.
TurboTax support is open Monday thru Friday from 5am to 5pm Pacific time.
See this TurboTax support FAQ for contacting support - https://ttlc.intuit.com/community/using-turbotax/help/what-is-the-turbotax-phone-number/00/25632
Support can also be reached by messaging them on these pages https://www.facebook.com/turbotax/ and https://twitter.com/TeamTurboTax
