Why is my 2019 AGI being transferred to my 2020 return?

I completed my taxes with Intuit and other vendors. I e-filed for 2019 with a different vendor than Intuit and it was accepted.

You need to enter your 2019 AGI to efile 2020.  If you filed somewhere else you need to enter the AGI from that return.  

You need your 2019 AGI to efile 2020. The AGI is on 2019 1040 line 8b. If you filed a Joint return you use the same AGI for each spouse.

Thanks for that answer. Since the online version of turbotax doesn't let you see the forms I didn't know that it was a line on the 1040 that needed to be answered. Stay safe and healthy!
