Thanks but the instructions for split gifts are:
Page 11 of the 2020 instructions for Form 709, Page 3, Part 4, Line 1 are quite clear:
Enter only gifts of the donor. If gift splitting has been elected, enter only the value of the gift that is attributable to the spouse that is filing the return.
Also, Line 1 on Part 4 states "Total value of gifts of DONOR"
