You can only file one form 2555. You may list either employer as your employer on the form (generally, I suggest the one where you earned the most income.) You will combine the income earned from both when reporting your income.
However, if you lived in more than one location, you can make adjustments to the housing allowance portion of the exclusion to account for more than one location if the locations have housing allowance that are greater than the standard housing allowance.
In the housing allowance section of TurboTax, after you select your first location click on the blue button "Another Location" and then enter the number of days in which you resided at the second location. TurboTax will prorate the amount based on the days at each location for you.
