When can we start e-filing 2020 amendments?

[caroljo]

I have a client who brought me his 2019 tax return.  Neither of us noticed that it was for the wrong year.  IRS did notice and I have to file an amended return.  Does anyone know when I can do that?

So You want to amend a 2019 return  or you entered a 2019 W2 into a 2020 return and need to amend 2020?

I thought the 1040X was final in 2020, have you tried to use it?

[caroljo]

I could use it, but I wanted to e-file it.  Are we going to be able to do that?

It should be working....are you not able to Efile an amendment for 2020? I haven't had a reason to try one yet, but if the form is final, it should be working, no?

When I try to e-file, it says the return has already been e-filed.  Maybe I am doing something wrong.

I just now figured it out.  I can't do the state (AZ) but will just have to mail it.  Thank you.
