I used Turbo with the "foreign earned income exclusion form 2555" for a few years and it worked well. I was not paying foreign tax at that time.
I gave up on Turbo when I started to pay foreign income taxes because I knew more about the form 1116 than their online chat help. Their program generated 0 and they proposed the itemised deduction method instead of FTC method using form 1116, which I found out was disadvantages to me after I paid them to generate my forms.
I redid the tax with H & R Block Expat online service (set up by country of residence for servicing different time zones) and their staff understood the form 1116 well, with very prompt service and support at a reasonable price. They did a great job, I will stick with them.
Good luck, I am unsubscribed to the chat as I will not be using Turbo anymore.
