What tax year do you need to amend? If you are asking about a 2020 return that you just e-filed you cannot do anything to it now while it is in pending. Are you asking about 2020 or some other year?
Yes the 2020 I did it with my email and it didn't seem right so I used my other email to create a different account as ND did it again and it was perfect I finished everything but at the end when I filed it said Abner account used same SSN and now I don't know what to do
Sorry if you already submitted the first one you have to wait until the IRS accepts or rejects it which won't be until they open on Feb 12 this year. So you have to wait. If they accept it then you have to wait some more until they finish processing it. Then you can amend it. If they reject it then you can fix it and resend it. So do not change anything until you know if the IRS accepts it.
