Retirement tax questions

@DanaB27 

 

If go back trying to Turbotax online to fix the 2020 amended return , it will not allow me to do so, instead it asked me to download a desktop version which I tried and only has the option of mail rather than e-file.

 

Interesting enough, I successfully e-file my 2021 amended return and get accepted by IRS.

 

Is there a way to enable my online amendment capability for tax year 2020?

 

Too many questions, thank you...
