Can you help find my last year agi or tell my why you say I haven't used turbo tax before?

I have purchased and used turbo tax every year for the past 10 years. I used it last year. Need last years agi. I get the message that I have not used turbo tax before. Can you help?

I tried using the solution that was sent and found there is only one account associated with the e-mail address used for the  last several years. Including purchasing this product. Still can't obtain last years AGI
