Form 1116 is available from the IRS (https://www.irs.gov/pub/irs-pdf/f1116.pdf), but TT cannot be used to complete it (until they fix their software). You would have to complete Form 1116 manually. Also, you would have to submit your taxes on paper. You can find the 1116 instructions online, but completing the form can be a bit daunting. I have completed it that way multiple times but I have also made mistakes several times. For example, Part 1 line 3 has several items that are not straight-forward.
I used H&R Block for years but this year I could not purchase a version with a CD, so I have been using TT. Until about two years ago HRB did not support Form 1116 so I had to complete it manually. But when they did "support" it I could not file electronically. I prefer the HRB interface to that of TT.
