What exactly do you mean by filling out your foreign income "manually"? Did you enter it as "Employee Compensation Not Reported on a W-2"? That's not for foreign income.
To enter foreign earned income in TurboTax, in the Search box type "foreign income" (without the quotes), then click the link that says "Jump to foreign income." When TurboTax asks what form the foreign income was reported on, select "A statement from my foreign employer (could be cash)." If you select the option to exclude your foreign income, TurboTax will ask questions to determine whether you qualify, and will fill out Form 2555 if you do qualify.
