Form 8858 is a form not supported by Turbo Tax so information that you would place in this form should not populate in Schedule C. You can download the form here.
Since you are filing as a Dual-Status citizen, you will need to print and mail your return. Based on this fact, I would suggest to report the information on the 8858 for the full accounting year. You might include a written statement in your return that you are disclosing reporting the 8858 for the full accounting year but your Schedule C income only reflects income you earned as a US citizen. This should be evident though means you are filing as a dual-status citizen but an additional statement should clarify your position.
Please read the link I have included below from Turbo Tax on how to file as a dual-status citizen.
