Get your taxes done using TurboTax

I have tried to e-file my 2019 taxes three times but each time it is rejected. The reason given is that the AGI from my 2018 taxes is not correct. I checked and the AGI for 2018 is correct. What should I do? I would prefer to e-file rather than mail my tax returns. Please give me a phone number that I can call to speak with a Turbo Tax representative.
