First, a disclaimer: I know nothing of TurboTax.
Are you going to be earning similar or greater amounts in years to come? In other words, was this a one off year? If, in future years, your earnings will remain above the FEIE limit, it may be time to make a big jump and forget entirely about using Form 2555 and start using only Form 1116 (both general and passive). You may find this to be to your advantage due to the banking of carryover credits. You should still owe $0 (generally speaking) due to the amount of tax paid to the UK on your salary. Run TT both ways to confirm.
If it's a one off year, you may decide not to do the general and passive 1116's only since once you elect not to use 2555, you cannot go back to using it for 5 years.
