I received a notice from IRS saying that my tax file is missing for 2019. I downloaded the pdf file from TurboTax and it was almost empty. What shall I do?

I always use the turbotax online and bought its product on for tax return of 2018, 2019 and 2022. However, I could not find the tax file for 2018 on turbotax online and that of 2019 is almost empty (only standard deductible was filled. All others are BLANK). Moreover, the status of my 2018 is missing and that of 2019 is printed. Since IRS asked me to send the copy of my tax return for 2019. Are there any suggestions?
