Can i put 0 for AGI in this scenario ?

My agent filled my last year tax return but he did not e-filed it and I did not mail the paperwork, but I paid the amount I owed the govt online. Now filling my tax this year, I needed my AGI, checked my transcript for last year and it shows that my last year's tax return is non-filed. What do i do now?

Can I put 0 for AGI ?
