Omission in 2019 form 8606, so info is not flowing into 2020 return, what should I do?

Hello, I'm finishing my 2020 return with Turbo Tax CD version. I did a Roth backdoor conversion in 2020 contributing to 2019 and 2020 in the same year. I did not have any money in a Traditional IRA in 2019. My 2019 Return includes form 8606 but I realized I did not fill out the form correctly since the information is not flowing into my 2020 return.  What should I do to fix this?

 

On form 8606, I entered 7,000 on line 1 and zero for line 2.

On line 3 and 14 I entered the 7,000 and stopped there. Can I print out a new form 8606 and send an amended form?  Do I make this change in Turbotax 2019 to carry to 2020?   

Do I need to send an amended 1040 for 2019 to reflect the conversion? Or just the 8606?

 

Thank you for your help in advance.
