In the T2209 form, when calculating the Net foreign non-business income, should we subtract the retirement plan contribution from my total foreign income?

I am using TurboTax to report my US income and claim the foreign tax credit. Let's say my total US income is 10K and made 2K contribution to my US 401k plan. What is my foreign non-business income on the T2209 form? Is it 10K or 8K? Currently, Turbotax automatically files in 10K, but based on the T2209 instruction, net foreign income should subtract the pension plan contribution
