Tax return from last year

My daughter was locked out of her turbotax last year after someone tried to do her taxes for her and no matter what she does she cant get in and wasnt able to file last year and cant figure out what her AGI amount was and had several different w-2s that she now can't find or get ahold of anymore. Also she wasn't sure what to do for this year and never did her taxes. Can u please help me and explain how we can get back into her account and finish her taxes for these 2 years? Thank you
