Gift Tax Form 709 - Reporting Prior Gifting

Reporting prior gifting on Gift Tax Form 709:

For Schedule B (Gifts from Prior Periods)

I realize the final value comes from the Schedule B Worksheet.

Do I report the actual amount or the amount from Line 3 on Schedule A, Part 4 - Taxable Gift Reconciliation?

Example:

Actual gifting = $100,000

Line 3 on Schedule A, Part 4 =$100,000 - Exclusion of $54,000 =  $46,000

Reason for asking is - Page 1, Part 2 Tax Computation, Line 3 states "Total Taxable Gifts" = $46,000.

Thanks in advance
