After you file

I looked at the chart. The chart tells me it's TurboTax that is not ready and apparently putting the onus on the IRS.  That doesn't answer my question as to why TurboTax is not ready. We can keep going round and round. I just want to know why TurboTax is not ready at this point in time when the IRS is accepting e-filing of 1040x 2020 now. Have a good year...out.
