Should I submit amended 709 return for error in line 8 ?

[chistapeter]

Hi there,

In my last year's 709 form (for year 2019), I mistakenly entered 4,417,800 in column C, Schedule B instead of the amount from line 12 or previous years. (2018)

This resulted in corresponding wrong calculation in lines 9 and 11, though line 12 and 14 remained unchanged. 

I already sent the 709 for year 2020 today.

Please confirm if I should send amended 709 return for last year (for year 2019) for this error.

Thank you!
