I made a new account with the same email I used to file last year, now I am unable to find last years AGI. I do not know how to find my AGI from last year now.

I have an email from TT last year that confirms that it is the same email I made a new account with. I do not know why it would allow me to make a new account with the same email address. Is there any way to find the old account and log into that one to get my AGI?
